So, maybe you can create a small character device driver and implement
the mmap method for this driver, this will allow you to share a piece of
memory between kernel and user-space without resorting to Xenomai
services. There are examples of this sort of things in the "Linux
devices drivers" book.

Ok. Got it now. So, mono probably calls munlockall. Another solution is
to look for this munlockall in mono sources and recompile mono without it.
