Re: can't mlockall() more than 128MB, is this a kernel limitation?

[David Hinds]

Actually, since the present test is only done on the number of pages
to be locked at the time of the system call, it is nearly worthless.
You can already mlock more pages than the "limit": just do mlockall()
with MCL_FUTURE, and allocate your big block of memory afterwards.
