locate-dominating-file (or rather some equivalent code) is also used in
VC to detect the revision control system used for the file.
It's actually used 5 times there (once each for Bzr Git Hg Mtn Arch), so
are you sure only the one in project-find-settings-file costs us
the slowdown?  If so, it's probably just because it's the first one run
and the others benefit from the OS's cache.
