| While you could make {exec cp ...} work, fcopy will GREATLY
| simplify your burden.
My experience is that fcopy used on *files* basically blocks the app,
since the channels are always readable/writable, and thus the app is
busy re-firing the fcopy-continuation commands, unless you introduce
an artificial delay (and thus delay overall copying time).
I'd stick to opening a read-pipe to the 'cp' (or even a tclsh running
fcopy :-) and trigger on the EOF on that channel.
