[PATCH v2 0/4] introduce test suite "parallel" mode

[Tom Tromey]

Revision 2 of the initial parallel mode test suite change.

The original thread is here:

    http://sourceware.org/ml/gdb-patches/2013-07/msg00382.html

I believe I've addressed all comments from the first series:

* Reordered the series so the caching procs come earlier.
  Consequently, moved all the parallel bits out of patches 2 and 3
  and into patch 4.

* Various inotifywait fixes.

* Disable parallel mode if remote-host.

* Updated gdbint.texinfo.  Patch #4 now needs a doc review.
