CVS commit: src/sys/rump/librump/rumpkern

["Antti Kantee" <pooka%netbsd.org@localhost>]

Module Name:    src
Committed By:   pooka

Modified Files:
        src/sys/rump/librump/rumpkern: vm.c

Log Message:
Make uvm_pagealloc_tele() fail if the request can't be immediately
satisfied.  This allows the caller to unlock the object and the
pagedaemon to avoid deadlock even if ~all memory is consumed by
one vm object.  This in turn makes is possible to copy a large file
into a rump kernel with a 10MB memory limit (where large >> 10MB).
A little more tuning will be required to avoid the pagedaemon
hitting the sleep-and-retry path, though.

+ fix some outdated unrelated comments
