Closing windows left application running in process list about puttycyg

[GoogleCodeExporter]

I have the exact same issue.

Further, both conhost.exe and cthelper.exe are left running, in addition to the 
child process passed to puttyCyg (in my case, Irssi.)

Reproduced with:
PuTTYCyg 20101029
Windows 7 Ultimate 64 bit, Version 6.1.7601
Cygwin1.dll v1.7.7

I've just discovered this same behavior.  I was seeing a lot of conhost.exe in 
the task manager.  After doing an hour's research I figured out they were being 
left by X(ing) out of putty.  If I issue an “exit” to close the window 
everything gets cleaned up properly.

I also discovered that if you X(out) and then login and find the old bash 
session and kill -9 that session it will destroy the conhost task.  You can not 
kill -9 the conhost task directly.  Not sure if this is a putty or cygwin 
issue.  I too am running windows 7.
