Agreed, as it only helps a little lets MFC after 4.7

okay

I have just discovered that if you start matlab without the Jave VM
running it exits cleanly:
slave$ /ide3.g/matlab6p1/bin/matlab -glnx86 -nosplash -nojvm

To get started, type one of these: helpwin, helpdesk, or demo.

>> plot(1,2)

slave$ ls
kdump_matlab ktrace_matlab_helper.out
kdump_matlab_helper noX11/
ktrace_matlab.out
This is _without_ the TIOCSCTTY patch.
Will dig a bit more, but I have already noticed that matlab -nojvm
doesn't spawn any threads. However, with the JVM about four or five
threads are created. I suspect something is broken in the killing of
threads.
