 i have a process (vmware running XP) and it runs ok

 out of my 4GB RAM), it
 runs very slowly.
 i susspect that the problem is that linux swaps part
 of it.
 how can i make this process's memory unpagable and
 unswappable, i.e. always
 resident in real mem ?
mlockall ?
You can invoke mlockall in the shared library and run
your VMWare with this library LD_PRELOAD'ed
