I did some more testing.

It seems that the hang problem is specific to python only. I tried the
Windows Server 2008 with Hyper V RC1 version which is a later build
than the enterprise RC1 version. The python hang persists. However,
cygwin installation with or without python goes through without a
problem. Python hangs when opening the interactive interpreter shell
or when running a python script. Commands like "python --help" work
just fine.

How could I debug it further? What tools do cygwin developers usually
use to figure out where the problem is? I tried using WinDbg but could
not make much sense out of it.
