20060521 snapshot, Ctrl-C, and Windows processes

[Igor Peshansky <pechtcha at cs dot nyu dot edu>]

Hi,

Noticed a problem today: if you start a Windows process in bash and press
Ctrl-C, the Ctrl-C will be delivered to the process, but then bash (or the
Cygwin wrapper that waits for the Windows process) will simply hang until
the Windows process terminates.  If the process does not terminate (e.g.,
"ping -t"), bash will hang until Ctrl-C is pressed 10 times (the delays
between the consecutive Ctrl-Cs don't seem to matter).

Steps to reproduce:

In bash, type "ping -t cygwin.com", then, after a couple of ping results,
press Ctrl-C.  The process will hang (here's the screenshot):

$ ping -t cygwin.com

Pinging www.cygwin.com [209.132.176.174] with 32 bytes of data:

Ping statistics for 209.132.176.174:
    Packets: Sent = 2, Received = 2, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 82ms, Maximum = 83ms, Average = 82ms
Control-C
^^^

Pressing Ctrl-C 10 times at this point returns to the bash prompt.
This is with the latest (20060521) snapshot, as well as with my own CVS
builds.  The output of "cygcheck -svr" is attached.
