Comment (by Deewiant):
I just realized an error in the patch against `process`: a critical
section object is now initialized and deleted each time
`runInteractiveProcess` is called. This makes it completely useless since
each thread gets its own critical section!
It should be made into a global, initializing it only once. Deleting it is
probably unnecessary since the OS will free it when the process exits, and
you can't be sure it won't be reused until that happens anyway. I defer
doing this to someone who knows more about how that single initialization
can be performed.
