Log Message:
Avoid parallel allocations within the same allocation group

When large files are writting in parallel, allocating the space for
these files within the same allocation group can cause severe
fragmentation of the files.  By keeping track of open, growing files
within an allocation group, we can force other new allocations into
a different allocation group to avoid causing fragmentation.
