The obvious owner of a ksycoca shared memory would be kded.
It's not supposed to crash, in theory :)
In production kde3 systems kded doesn't crash -- otherwise you lose too many services,
and it doesn't automatically restart itself (I guess it should).

Assuming kded is always running, we wouldn't leak resources if an application merely
using the shared-memory-for-ksycoca (in a readonly way) crashes, right?
