Alexander Motin b17bfcde3d 9018 Replace kmem_cache_reap_now() with kmem_cache_reap_soon()
illumos/illumos-gate@36a64e6284

To prevent kmem_cache reaping from blocking other system resources, turn
kmem_cache_reap_now() (which blocks) into kmem_cache_reap_soon(). Callers
to kmem_cache_reap_soon() should use kmem_cache_reap_active(), which
exploits #9017's new taskq_empty().

FreeBSD does not use taskqueue for kmem caches reaping, so this change
is less dramatic then it is on Illumos, just limiting reaping to 1 time
per second.  It may possibly be improved later, if needed.
