Uhmm a v. nice idea may be to build a performance auditor module, that
print into syslog statistical data about number of times a call is made
and average time to perform each call by the underlying filesystem.

Terry if you can do that and contribute it back it would be wonderful,
will help other VFS module writers to profile custom vfs modules.
