I think this has no aim, RAM tests should be done during booting, but
u could try to disable interrupts while in kernel mode 'cli' which
will prevent any further context switching, then try to do whatever
you want, finally enable interrupts back 'sti'.

That's my two cents. I don't whether it will work or not.
