What may be even more relevant than reading from channels
that likely won't send data, anyway, is to call .waitFor()
on the process returned by the .exec(...)-call, in order to
ensure that "After process run" is really printed after the 
run, instead of already after merely being kicked off.

Reading from the error channel, like Arne suggested, might
still be a good idea - unless you really don't care about
any failures of uuencode or mailx.  Logging errors could also
be done by ">>/tmp/debug-uuencode-and-mailx.log 2>&1" added
to the little ksh-script.
