Had a need to run ASAN+UBSAN and
it works perfectly fine for me with
version 0.2.4.27.

Required a minor patch to convert
a single common variable 'incoming_queue'
to extern.

Performance hit was not as bad as I
thought from the earlier try, but bad
enough that I limited the instrumented
modules to only what's necessary.
