1351 requests at most at a time (for a running process)

48618

0xffffffff82e21f2d : int3_magic

This seems to be the most problematic, and happen even if over ~1314 requests
are made.

add2line seems to return the source file in that case as:

arch/x86/kernel/alternative.c 29


that is instead, of what it normally returns for a single request (this, is
still broken info as no such file exists and and it should not return a
filename without a line number):

alternative.c:?
