Hi,
I have been trying the pipeTestService.py in win32\demos\service, sending it
single messages with the pipeTestServiceClient.py script - that works fine.
But I get errors when trying out the multi-thread multi-message options
( -t <n> -m <k> ). I am running the script with ^R from within PythonWin.
pipeTestServiceClient.py -v 'test test test'
>>> Sending 'test test test'
Server sent back 'haimo (on thread 172) sent me 'test test test''
pipeTestServiceClient.py -t 10 -m 20 -v 'test test test'
>>> Sending 'test test test'
Server sent back 'haimo (on thread 132) sent me 'test test test''
Spawning 10 threads each sending 20 messages...
Traceback (innermost last):

1024, NMPWAIT_WAIT_FOREVER))

etc...
Am I doing something wrong, or does that really not work?
I'd like to be sure that the examples work before I adapt them to my own
programs.
