I've just had a user here (no,  it wasn't me) issue a '/WHOIS a' to
a LISTSERV whose signup file  must have contained over 1,000 names.
Maybe there  should be a  threshhold on  the amount of  output this
command can  generate  and if  it is exceeded,  send it via  a file
(means  more CPU, traffic, etc.) or send a message  back to telling
the user  to broaden the search string???
