i've attached mlock-test2.cc that should test this theory. The code
breaks up the mlock-ed region into 8 equal pieces and does mlock() on
them separately. It's basically a lock-break done in user-space. Does
this change the nature of xruns?

This does change the xruns.  I have to `mlock-test2 8000' to produce
any xrun at all, and that only produces a 2-300 usec xrun.  With
mlockall-test the threshold to produce an xrun was ~1500.

did you try mlock-test.cc too? Just to make sure that mlock-test.cc is
equivalent to mlockall-test.cc.

That attachment was also missing.
