Better Solaris fix...

["Robert S. Thau" <rs...@ai.mit.edu>]

Well, it turns out that locking the scoreboard file (as per previous
patch) doesn't work directly, because tmpfs doesn't support locking of
*any* sort.  It does appear to work (I'm running with it on port 80)
with the scoreboard file in /usr/tmp, which is generally not a tmpfs;
revised patch below.

Sun Quality Software... gotta love it.  Waaaaaahhh....
