Hi,
I've kinda reported this before (mlock issue) but this backtrace is
slightly different.
I'm fully prepared to say this is a kernel problem but this is with the
rc9 of 2.6.31 so figure is worth mentioning again and perhaps getting a
clearer insight so I can report it to our kernel guys who can take
appropriate action if needs be...

The program is running. Quit anyway (and detach it)? (y or n) y
