Fixed vlimit.  This program lets us set various per-vserver limits. In
particular, we can now set nproc limits (aka the vserver equivalent to
CKRM numtasks).  There are other limits that apparently just work, too,
such as resident-set-size, number of open files, etc., that I'll start
playing with, too.
