STANDARDS
     The sem_open(), sem_close(), and sem_unlink() functions conform to
     ISO/IEC 9945-1:1996 (``POSIX.1'').

HISTORY
     Support for named semaphores first appeared in NetBSD 2.0.

According to

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/uipc_sem.c?rev=1.22&content-type=text/x-cvsweb-markup&only_with_tag=MAIN

SEM_MAX is 128 since 2007, and dynamically adjustable (no reboot).

It looks like the sysctl (read/write) option is kern.posix.semmax.
