Added flush of output on exit. On some UNIX's using the native library
resulted in no output when the output was redirected until this was done.
Redirection is important because runtest redirects test output.

Added support for numerous environment variables which make it easier
to run a multi-node system using a single executable and to tailor
the size of the workspace and heap.
