[svn-r10978] Purpose:
Interim checkin of code changes moving management of the is_dirty flag
into the cache code.
Description:
Prior to this checkin, management of the is_dirty flag was handled
above the level of the metadata cache. This can no longer be allowed,
as it introduces a race condition in the proposed fix for a cache
coherency bug in PHDF5.
Solution:
Move management fo the is_dirty flag to the cache code proper.
Entries are now marked as dirty via a flag on the unprotect call.
Platforms tested:
h5committested
