/*
** Modified version of GUSISIOUX.cp especially for Python.
** Changes (by Jack):
** - Optionally delay the console window until something is written to it.
** - Tell the upper layers whether the last command was a read or a write.
** - Tell SIOUX not to use WaitNextEvent (both Python and SIOUX trying to be
** nice to background apps means we're yielding almost 100% of the time).
** - Make sure signals are processed when returning from read/write.
