Ok, can someone explain to me that hard limit of 8MB on x86?  I wasn't
aware of it at all.  Is this built into LinuxThreads in some other
place, or is it a kernel limitation?  I am aware that many
distributions set the default stack limit to 8MB (and I think that is
good).

The patch could of course also be applied with MAIN_STACK_SIZE_MAX set
to 8MB, a fourfold improvement over the current situation.
