Coroutines are allowed to create new threads.

Coroutine stacks do not grow automatically but they have 1 MB, which
should be enough.

There are a number of other things that could be wrong here -
missing/incorrect thread synchronization, the shared libraries you are
importing messing with the environment (signal masks, signal
handlers), etc.
