The service design itself needs work, but for now the problem can be
avoided by fixing the /etc/init.d/IIim script. Unfortunately in the
course of investigating this bug, I realized that it causes 100% CPU
usage and total failure of htt's functionality in non-obvious way. =(
Setting FC2BLOCKER and rebuilding now, but it is up to Elliot if he
would allow this update into FC2 final. If not then this should go
out in the first batch of FC2 updates immediately upon release.
