Yes, but unfortunately not much will happen. If you can provide a patch, I
will be happy to look at it and get it in, but I doubt I will find the time
to firstly research it, then implement it.

Sounds great! :) Just make a patch or if necessary, send me a the complete

You should find an 'example_nt' directory somewhere (maybe only in the
Python sources). This will create a .pyd - but a .pyd is just a .dll with a
funky extension :)

As above - I've no shortage on nice things to do :)

Thanks - I've checked that in.

I believe this flag will simply allow these services to *create* a console.
Eg, a service with this flag can call CreateProcess, and you will see the
new process' console. When the parent service does not have it set, you
don't see the console. The win32 console API could also be used by a
service to create a console, but I'm not aware of how you can get a console
for the service itself.
