description="""
The library functions popen(3) and system(3) are used to create a new shell
process and (in case of popen(3) set up IPC channels to the new process).

Currently they are implemented using fork(2), execve(2) and do a bit of
astonishing complex internal bookkeeping.

It should be possible to simplify both implementations using
posix_spawn(3) and associated helper functions.
