SVN commit 935291 by dfaure:

Make ksycoca threadsafe. Summary of changes:
- OOo design for the 4 ways to access ksycoca data (mmap, qfile, shared mem, dummy qbuffer),
  which also allows to have a KConfig key for choosing the technology to use.
- per-thread KSycoca::self() and per-thread sycoca factories, using QThreadStorage.
  This way ksycoca updates are handled by each thread at its own pace (assuming it has an event loop).
- threaded unit test: two in kservicetest, plus the standalone ksycocathreadtest.cpp

=> KRunner and kdevelop (and others) can now use KService and KMimeType and K*TypeTrader from threads without a mutex.
(If in doubt about races in your threads, I suggest valgrind --tool=helgrind, using valgrind svn preferrably.
You'll hit some races in Qt that I reported recently though)
