this kind of control. As of use of mlockall(MCL_FUTURE) how can I make
sure that all memory allocated behind my application's back (by dynamic
linker, libraries, stack) will be locked otherwise?

If you add this flag you can't do that anyway - some library will
helpfully start up using it and then you are completely stuffed or will
be back in two or three years adding MLOCKALL_ALWAYS.

Agreed, mlockall() is a very bad interface and should not be used for a
plethora of reasons, this being one of them.

The thing is, if you cant trust your library to do sane things, then
don't use it.
