Alpha version of GNU Parallel 20110719 released

[Ole Tange]

The GNU Parallel 20110719 alpha release can be fetched at:
http://alpha.gnu.org/gnu/parallel/parallel-20110719.tar.bz2

Please test it thoroughly so we are sure nothing is broken. parallel
passes the testsuite, so parallel should be production quality.
However, niceload has gotten a major overhaul so it might be somewhat
broken. Thus you should concentrate your testing on niceload.

New in this release:

* niceload: --hard will suspend a program if a limit is reached - as
  opposed to just slowing the program down.

* niceload: --soft will slowing the program down - as opposed to
  suspending the program completely.

* niceload: --run-io will slow down a program if disk io goes above a
  certain limit.

* niceload: --run-load will slow down a program if loadaverage goes
  above a certain limit.

* niceload: --run-mem will slow down a program if free memory goes
  below a certain limit.

* niceload: --run-noswap will slow down a program if the computer is
  swapping.

* niceload: --start-io, --start-load, --start-mem, --start-noswap will
  defer starting a program until the system is below the limit.

* --io, --load, --mem, and --noswap sets both --run-* and --start-*.

* niceload got a major rewrite and is now object oriented.
