It should be noted in the description that the zwgc process does not
wait for the process started by "exec" to finish. Therefore, if it is
intended to produce output on stdout, such output may be intermixed if
two or more messages are received in a short time period. (The only
way to force the output to be sequential seems to be to create an
execport, loop printing its output to stdout, and then closing it when
EOF is detected. Having the subprocess print to stderr might work,
but seems like another wrong solution.)
The `port' variable is, I believe, a use of the word `port' distinct
from its use in the rest of the manual page. This should be made
clear.
An explanation of what happens when an attempt is made to read from a
port at eof would be helpful (including the _exact_ error text, if
checking $error is the only way to be certain).
