[svn-r19247] Description:
Bring r19246 from Coverity branch to trunk:
Improve metadata "accumulator" for files to track the dirty region within
the accumulator data. This allows the accumulator to drop clean data and
reduces the number of I/O operations when it is dirtied.
This is progress toward Bz#1142 - speeding up the fheap test (which it
doesn't help much, actually, but it does help other aspects of file I/O).
Tested on:
