Description of problem:
Currently the htt IIIMF server runs a root. Since there are
security concerns for this client-server system, the server
should be run by a non-priveleged user.
Steps to Reproduce:
1. service IIim start
2. ps aux|grep htt$
root 9364 0.0 0.0 3068 272 ? S 10:21 0:00 /usr/lib/im/htt
iiimf 9364 0.0 0.0 3068 272 ? S 10:21 0:00 /usr/lib/im/htt
For comparison: Canna's cannaserver runs as user bin,
and FreeWnn's jserver runs as user wnn.
