For people that turn off debug on main, should WITH_PTHREADS_ASSERTIONS be
turned off?
e.g.
/etc/src.conf:
WITH_MALLOC_PRODUCTION=yes
WITHOUT_LLVM_ASSERTIONS=yes
According to commit 642cd511028b running WITHOUT_PTHREADS_ASSERTIONS improves
mutex performance by 5-18%. So yes if you want maximal performance on HEAD
you should probably turn this off.

Add description for WITH_PTHREADS_ASSERTIONS
This option is turned on by default in -CURRENT but will be turned off
in 15-STABLE; this description will land in the src.conf(5) man page
in that branch.
