--- Comment #4 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to Conrad Meyer from comment #3)
Total number of kqueues per uid is limited by rlimit(2) RLIMIT_KQUEUES with no 
default limit.  Global system number of kqueue timers is limited by sysctl
kern.kq_calloutmax with the default value 4096.

TIMER_MAX defines the number of elements in the per-process structure, so
bumping it arbitrary is not possible without reworking the code.  It probably
can be increased to e.g. 64, but I doubt that this would be useful.
