Dunno. The IPC code uses ushrt as the type for uid... couldn't
find anything else that does. Is this vestigial?
I'm CC-ing this to 'freebsd-hackers' since I think we're outside
the pervue of 'freebsd-isp' at this point...
The question is "What is the maximum UID?". Its either a 2 or 4
byte unsigned integer. The filesystem seems to accept 4, pwd_mkdb
complains about larger than 2 but lets you do it...
