Updated comm counts for alloc_all cyclic and replicated
Fix problems in our file timestamp adjustments.

We were still seeing problems with attempts to rebuild things, due to
losing the file timestamp information when we put the untarred sources
into the repository and get them back out.  This change seems (cross
fingers) to solve those problems.

While here, I removed the sleep commands, because I don't think they're
actually needed.
