Only because you haven't noticed the bugs yet...  for instance,
session timeout is broken (commented out, actually) in your patch, so
broken backends and / or clients will bog you down.

That sounds like a good idea.  Even better if you can submit an
isolated patch :)

Probably not a good idea unless sendfile() semantics are significantly
better on Solaris than on FreeBSD and Linux.

There are issues here as well; the semantics are subtly different from
OS to OS.  For instance, what happens if separate threads in the same
process try to lock the same file?  It's even less fun if you take
into consideration systems that support both.
