I'm also seeing problems with ULE on a dual-socket quad-core Xeon 
machine with 16 logical CPUs. If I run "tar xf somefile.tar" and "make 
-j16 buildworld" then logging into another console can take several 
seconds. Sometimes even the "Password:" prompt can take a couple of 
seconds to appear after typing my username.
