It would be interesting to see if you notice any speed improvements by mounting
any directory containing cygwin executables with the '-X' option.  This informs
the cygwin1.dll v1.1.5 that it can pass arguments around using UNIX conventions
for argv and the environment.  So, it doesn't have to spend time quoting arguments
or munging environment variables.

For directories containing non-cygwin executables, mounting using the '-x' option
should also cause a slight increase.  That would stop cygwin from opening file
to look for a '#!' in the case of non .exe files.  This is also the case for '-X'
mounted directories, of course.

The '-x' option actually should work for 1.1.4, too.

Also, check out the 'ps -W' command.  It lists all processes rather than just
Cygwin processes.

Now, if only it all worked on NT 3.5... :-(
