Why should we forget about "the last one"? Do you mean 1.3.9 solved your
rxvt issues?
I've 1.3.10 and rxvt 2.7.2-10 and I can freeze rxvt in many different
ways: here are 2.
This is on XP Pro and used to happen with earlier cygwin/rxvt versions
too.

Freezing way 1
  C:\> C:\CygWin\bin\bash --login
  Livio AT MOLOCH ~$ rxvt
  \u AT h \w\$ Ctrl-D
This makes rxvt crash, XP display the "send error report" dialog, and I
get a fresh rxvt.exe.stackdump file.
Note that the following doesn't crash my rxvt
  C:\> \CygWin\bin\bash
  Bash-2.05a$ /bin/rxvt
  $ Ctrl-D

Freezing way 2
  C:> C:\CygWin\bin\rxvt.exe -sr -e /bin/bash --login
  Livio AT MOLOCH ~$ mkdir a
  Livio AT MOLOCH ~$ cd a
  Click on the Windows upper right X button to close the rxvt window
Rxvt terminates but bash is left as a defunct with handles still open on
dir "a" so that I cannot remove dir "a" from windows/cmd (you can see
the hung bash with CMD.exe "tasklist|findstr bash", WindowsTaskManager
Processes, SysInternals ProcessExplorer, etc...)
Note that if I close rxvt typing Ctrl-D (instead of clicking the
button), both rxvt and bash terminate properly.

The samples above are on XP, I don't have cygwin on 2k anymore to test
if these tests works exactly the same on 2k, anyway rxvt used to crash a
lot on my 2k machine too and often, after the crash, I got 100% cpu load
by the hung processes (but maybe this was with an earlier cygwin
version). On XP I never experienced the 100% cpu issue.

Regards,
Livio
