Rob,

This is not to diminish the effort of everyone involved in any way, and I
hate to be the one to break the party, but the hang problem I reported
earlier (<http://cygwin.com/ml/cygwin-apps/2003-03/msg00548.html>) is
still happening for me.  I was able to reproduce it on large (in the
number of packages) downloads: the first couple of times setup hangs and
has to be restarted.  They aren't really hangs, either, as the "Cancel"
button works, and so does the "Window close" button...  I have the logs
from the hangs, but they don't tell much, only that the FTP transfer has
been started and hasn't completed.

Contrary to the message referenced above, it doesn't seem to be related to
the cut-off message problem, as that appeared in the log of the run that
didn't hang as well (but only when some packages aren't up-to-date).
I've attached to the hanging process with gdb and got a backtrace for all
threads (attached), but it wasn't very informative (to me).  Perhaps it'll
be more useful to someone else here...  I've also attached the
corresponding setup.log.full (bzipped).
	Igor
P.S. I've reproduced the hang on more than one machine, however, both were
Win2k.
