[ros-kernel] Bug in mdl changes

[Hartmut Birr]

Hi,

compiling ros on ros freezes while building the import libs. I've enabled
the non paged pool statistics. Usually I can see 3200 pages used by the non
paged pool at the end of the compiling. Printing the memory usage at the end
of PiDeleteProcess is currently not part of the cvs.
