Comment:

 Initial stab at it. I had to take the approach of keeping the value of max
 file descriptor locally in compat.c else `get_options` wasn't usable
 without a zillion compilation warning when including config.h.

 This has been tested on a relay with a limit of 4096 and it never went
 over 4064 (the OS limit minus `ULIMIT_BUFFER`) for more than an hour of
 testing (takes ~30 minutes to reach the limit).

 Branch: `bug16288_027_01`
