Not based on information so far.  Unless the problem is platform or
architecture dependent, which would surprise me, it's likely a problem
local to your machine.  I cannot reproduce it on WinXP x86.

You could try running 'strace' on it and look at the numbers on the left
to see where the big jump happens.  That would at least give you some
insight into what call is taking the time.  BTW, I'm not suggesting
you send the 'strace' output to the list.  Just if you want to see if
there's something there that supports your findings so far and what may
be involved.  My WAG would be <http://cygwin.com/acronyms/#BLODA>.  I'd
also recommend that any future problem report that you make follow the
guidelines found here: <http://cygwin.com/problems.html>.
