 	src/sys/rump/librump/rumpkern: vm.c
 
 Log Message:
 rump: Handle uvm_wait tickets like the real kernel does.
 
 This should avoid trouble in any path that calls uvm_wait_prepare
 with spin locks held even though it's not going to sleep in uvm_wait,
 of which there are probably many more than just rump_hypermalloc --
 uvm_wait_prepare is supposed to be cheap enough not to be worth
 conditionalizing.  (Perhaps we should measure that, though.)
