There are some strange failures in the Cygwin build of Emacs (search
the archives of this list for Cygwin-related problems).
Unfortunately, none of the Emacs maintainers use Cygwin (or even
understand enough about it to intuit the possible causes of these
problems), so we rely on volunteers and the Cygwin developers to debug
the problems and report their findings.  Sadly, most of the problems
reported here were so mysterious and hard to debug that we couldn't
find any useful clues, given the knowledge of the people who tried to
debug them and the (lack of) support from Cygwin developers (it sounds
like no one on the Cygwin list is interested in supporting Emacs,
because several messages posted there lately did not get any useful
response).

Can you run the hanging command under GDB?  (Several Cygwin users
reported great difficulties running Emacs under a debugger, that's why
I ask.)  If so, please try at least to establish where it hangs.

I think someone reported a similar problem and debugging revealed it
hangs somewhere in memory-allocation routines; this was solved by
either upgrading to a newer version of Cygwin or downgrading to an
older version, I no longer remember which.
