I've been running the (cvs head) cygwin1.dll built with -DDEBUGGING this
weekend and I've been seeing a sequence of debugging messages of the
following form:

  33101 [main] sh 2580 mark_closed: attempt to close protected handle void
memory_init():162(cygwin_mount_h<0xC4>)
  35958 [main] sh 2580 mark_closed:  by int
fhandler_base::close():769(get_handle()<0xC4>)

I'm unclear what triggers this (or what it means for that matter): I've been
having so much fun with an strace issue, I've not had the time to go any
deeper into this.

What I can say is that running the configure script from the cygwin src
directory generates *lots* of these messages. I've appended the head of such
a run to demonstrate.

I hope I'll be posting soon with something more constructive than this (that
is, if my current hacks get me anywhere at all).
