Yes, indeed this is an issue.  A multi-threaded program I'm working on
would want each thread to count separately - because the threads don't
know much about each other.  Samba is more likely to want all threads
treated as a single unit.

Even in a program like Samba, you can imagine a plugin architecture or
something where 3rd party add-ons spawn threads, and those 3rd party
threads want to monitor a directory they are using, independent of the
main Samba threads.
