replaced all calls to track_worker_status with log_worker_status, to make the purpose clearer.
removed a few dependencies on q->workers_in_state where possible.
Add support for utimensat and futimens.

Fixes #26.
Compatibility with RedHat 5.

This fixes that problem.

system and assuming workers have at least one core before they report
thier capabilities.

Improvements to test runner script.

Test still fails. I'm looking into it.
Error from master and foreman name likeness uses fatal function.

Add work_queue_enable_process_module, which causes work_queue_wait() to call process_pending()
every loop to check for child processes that have ended.  This allows makeflow to get a much faster
response for local processes without accidentally gobbling up child processes of masters that
don't know about or use process.h
move work_queue_enable_process_module from work_queue.h to work_queue_internal.h
forgot to add modified makeflow.c to commit 1eddf13d
Add asynchrony control to work_queue.
