 fail.  shared libraries link extremely quickly.  reverted to static,
trying this:

$ python evil_linker_torture.py 3000 400 200 500000

so that's 4x the number of functions per file, and 2x the number of
calls *in* each function.

just the compile phase requires 1GB per object file (gcc 7.3.0-29),
which, on "make -j8" ratched up the loadavg to the point where...
well.. *when* it recovered it reported a loadavg of over 35, with 95%
usage of the 16GB swap space...

running with "make -j4" is going to take a few hours.
