It appears that it is 64. This may be hardcoded in a kernel object
file as near as I can find. This is the soft limit. Hard limit is
256.

I would guess you can handle around 50 at that limit. If you have
the setrlimit() function, the server should bump this limit as it
adds VirtualHosts IF you have set HAVE_RESOURCE in conf.h for A/UX.

The problem I ran into was that the code in conf_virtual_host()
was not uping this limit for SUNOS.
