Correct for 2.0.35. It works for 2.2. fine here but I have the default
higher from other stuff. See below.

2.2.x its configurable at run time to suit your needs. See
/proc/sys/kernel/shmmax for the current limit. That is settable by the
admin. Its identical to the nbd setting for shared memory size limits on
solaris (the one oracle always makes you set) if you know it
