Subject: | profile locking at wrong level when re-reading file |
With the profile-sharing code enabled, the mutex protects the linked
list of prf_data_t objects and their refcounts. However, once one of
these objects has been acquired for a profile instance, it's used
without locking. Mostly it's read-only access, but if the on-disk file
has changed, the tree of nodes will be freed and rebuilt, with no mutex
protection.
