SKsh in 1.3 and previous used *only* temporary file pipes.  In 1.4 only
temp file pipes were supported but there was the capability to use
one (count 'em!) concurrent pipe at a time using the AmigaDos pipe:
handler.  I ran into an inexplicable problem with using more than one
at once (and no, it wasn't anything you'd probably guess like trying
to use the same name for >1 pipe).  I may switch to pip: instead of
pipe: for 1.5.  However, my system went belly-up pretty severely this
weekend so I am kinda stuck for the moment.   At any rate, it may be
in 1.5 but I can't promise it.
