Maybe the problem doesn't affect -current.  I first saw this bug in a
3-year old version of -current and thought that I verified that it
still affects -current.  In the old version, getdirentries() and stat()
are Giant-locked (not MSTD in syscalls.master), so I don't understand
why there was a problem.  In -current, msdosfs is not MNTK_MPSAFE, so
the problem shouldn't affect -current -- it is already fixed unbetter
by Giant-locking everything.
