Type signature popup stops working

I'm running Ubuntu 15.10 and Sublime Text 3 build 3083. The signature popup works fine immediately after starting sublime and writing some code, but after it pops up a few times it stops working (see my third comment for a gif showing what this looks like).

I can reproduce this behavior by simply messing around for a bit inside () blocks (i.e. writing first argument, quicking writing the second one, moving the cursor with my arrow keys etc) but often times the popup will stop working right after the first use and takes no effort to break it.

I've enabled debug level logging and the plugin gets stuck in some kind of infinite loop. This is what it prints out:

2016-01-25 15:23:45,962: 139954225895232: DEBUG: In on_scheduled for work scheduler
2016-01-25 15:23:45,962: 139954225895232: DEBUG: Timer elapsed while prior job running.  Deferring
2016-01-25 15:23:46,014: 139954225895232: DEBUG: In on_scheduled for work scheduler
2016-01-25 15:23:46,014: 139954225895232: DEBUG: Timer elapsed while prior job running.  Deferring
2016-01-25 15:23:46,065: 139954225895232: DEBUG: In on_scheduled for work scheduler

This shows up ad infinitum in my console after the popup stops working.

The regular autocompletition and everything else works fine but the signature tooltip never shows up again. I have to restart sublime to get everything back to normal.

I should also add that I was not able to reproduce this on a windows 10 machine despite trying very hard for a few minutes to mess up the popup. I was however able to reproduce it on another machine running Linux Mint 17.2 but it wasn't as easy as it was on my ubuntu machine.

Seeing how I struggle myself to reproduce this across machines running configurations different than my own the main problem cause is probably somewhere outside the plugin code. I don't know what this cause might be on my machine but I did however manage to find a quick fix. In work_scheduler.py I changed the three occurences of the blocking sublime.set_timeout to the non blocking sublime.set_timeout_async. After this change I can no longer get sublime to enter that infinte loop described above and the popup works fine all the time. I don't know if this is something that can make it into production but it works for me and I'm putting it out there in case someone else runs into this issue.

Can anybody else try this on Ubuntu 15.10? Inside a VM, I've installed a fresh copy of Ubuntu 15.10 32bit, nodejs v5.6.0, sublime text 3 build 3103, package control, and the typescript plugin and I can replicate this problem right away. It looks like arrow keys cursor movement is the one to break it.

Here's a gif displaying how this problem behaves (I start off writing the function call, and it works well. I then move the cursor using the arrow keys, and it breaks down.):

The error log is the one in my initial post. I've browsed the plugin's code quite a bit in the last few days but I can't tell why this is happening. The fix I mentioned above does work but I don't really have any idea why.
