Linux runs into the same problem as Solaris with non-serial accepts.
Patches to 0.7.3k to flock on the error log follow. This solves the
problem under Linux and have noticed no user visible problems with
loads >60khits per day.

I have not yet tested this under our Solaris machine, but will. (not that
you'd want to actually run a web server under solaris, but...)
