* now by default Gateways DO NOT SPAWN execution threads
you can call "remote_init_threads(NUM)" on an already instantiated
gateway, which will install a loop on the other side which will
dispatch each execution task to its own thread.
* execution is dissallowed on the side which initiates a gateway
(rarely used, anyway)
* some cleanups (hopefully)

ssh-stdout-confusion tests involving "os.write(1, ...)"

a test name got fixed, but when you specify "-S somehost"
then this will hang, so i am skipping the test for
now, this never worked.
