Hi,

is there some kind of limit regarding the number of concurrent pipes to external processes on Windows?
I'm spawning 16 processes and want to redirect the output to Stdout, but I get the following exception.
It doesnt crash when I spawn 8 processes.

Cause of Dump: Unhandled exception: out of threads
