* sp/mmap (Sat Dec 30 22:13:43 2006 -0500) 25 commits

Running this and the merge-recursive speedup I sent today locally.
sp/mmap needs relatively recent cygwin library (otherwise pread
is broken). No other ill effects noticed. Perfomance is bearable.

The default on Cygwin is now NO_MMAP.  I've disabled that default

I left it at NO_MMAP: wanted to see how bad pread performs.
No worse than mmap, as it seems.

in my own Cygwin environment and continue to use mmap() rather than
pread(), but I'm also running my sp/mmap change there.  I haven't
noticed a performance difference, but I also haven't tested for one.
IOW if there is a difference its close enough to noise to not be
visible to me as a user.

Confirm that.
