Yes. 

Can you confirm whether your patch addresses a problem Reini reported your
thread in Feb? It was this message: 
	http://sourceware.org/ml/cygwin/2005-02/msg00224.html 
...where Reini said:

My problem is similar - in Cygwin, Proc::ProcessTable reports some PIDs as
WINPIDs instead of Cygwin PIDs.

In terms of my testcase (attached to my first email), the effect is that the
get_pids method in Proc::Killfam.pm does not recurse down all descendant
processes due to inaccurate PID reporting by Proc::ProcessTable.

What is 'AIUIkill'? Did you mean 'kill -9'? Isn't SIGKILL a Unix signal? The
context of the original discussion was about killing processes by sending a
SIGKILL (please see: http://sourceware.org/ml/cygwin/2005-05/msg00550.html )
