Updating REGRESSIONS based on past several days

new regressions:
- lulesh-dense started failing in valgrind -- Sung was unable to reproduce
- noted cases in which I/O is dropped on the floor for CCE
- a few new cases of glob() failing with CCE for similar reasons to what we've seen elsewhere

new fixes:
+ maxTaskPar is now working on cygwin (thanks Greg!)

misc:
* a few other things came and were fixed -- these can be seen in the commits that make up this pull request
* noted other noisiness / annoyances in preparation for REGRESSIONS week
