+- Multithreading is now contained in the DWARF loader using a jobs queue and a

+BTF encoder:

+- The parallel reproducible BTF generation done using the new DWARF loader
+  multithreading model is as fast as the old non-reproducible one and thus is

+  The memory consumption is now greatly reduced as well.
