I have not investigated the root, but while developing code for the Linux kernel
or QEMU, I often have to disable many of semantic's features (all those
appearing on the Development menu) or otherwise emacs eats up all my cpu. Also,
sometimes I want to kill some large buffer to keep the semantic memory footprint
low (it generated lots of tags, either directly or through includes), but I just
cannot (I think semantic takes a lot of time to serialize its information to the
disk).

This is most probably fixable in CEDET without resorting to a new database
backend, but I just wanted to make it "public" (although it's probably well
known).
