It is an easy way to break spelld service remotely exist (unless you block 7001 port).
Moreover, the same situation can easily happens if you stop indexer by ^C while it
talks with spelld:
telnet spelld.host 7001
HELO
(wait a second)
^]q (quit telnet)
That\'s all. spelld is now running forever looping end eating all CPU time. No
requests to spelld are processed anymore.
Firstly I think that it happens because spelld not check what send() returns and add
here check for -1 error, but it not helps, looping reason is elsewhere.
