Thanks Mohan.

"Thread.join()" seems indeed the way to wait for another thread to finish.  I think
it's perfect now; and it works perfectly on linux. I've removed the silly
"Thread.sleep()" and replaced it:

		threadIn.start();
		threadOut.start();
		threadErr.start();

		//wait until process truly exits before looking at its exit value	

		mExitCode=process.waitFor();

		//wait until process all child streams have been processed	

		threadIn.join(0);
		threadOut.join(0);
		threadErr.join(0);

		//recover output now

		mProcOutput=threadOut.getOutput();
		mProcErr=threadErr.getOutput();


I just hope that it works on GCJ 3.3/win32 as well?
