Thanks for this pointer.  This API is not too difficult, but it
will require some work to port things.  Sam Leffler also pointed
me to sys/opencrypto/crypto.c, which makes good use of this API.

For the zone(9) man page, for the uma_zcreate() function,
it is not clear what the valid values of "flags" are.

The only place where flags is mentioned is with respect to
uma_zalloc: "the flags argument to selected flags as documented
     in malloc(9)."

However, the flags argument in uma_zcreate() does not take
the flags as documented in malloc(9).  Would it be useful to
update zone(9) with either:
  - text that says, go see the flags in <vm/uma.h>
  - document the actual uma_zcreate flags

The documentation in <vm/uma.h> is actually good enough, IMHO,
but referencing it in the man page would be nice.
