Is it possible that VSZ becomes smaller/lower than RSS in 'vserver-stat'
after starting some applications (JBoss and Tomcat with Active-BPEL
engine, see #1)?
------------------------------------------------------------------------
~ # vserver-stat
CTX PROC VSZ RSS userTIME sysTIME UPTIME NAME

Does my understanding of memory allocation fail or is this a bug?
