i booted a UVM kernel (same very -current sources as the non-UVM kernel
i successfully booted only hours ago) on my /240 and it didn't like me:

root file system type: ffs
init: copying out path `/sbin/init' 11
uvm_anon_add: can not allocate 50999 anons
panic: uvm_anon_add


this would have been while swapctl was running ... 


i'll have more details when i look deeper at it.
