/dev/urandom takes about 38 seconds on a P5/133. It is useful
to be able to kill such reads almost immediately. Processes
doing such reads are now scheduled so their denial of service
is no worse than that of processes looping in user mode.
code when examining their fix, which caused my code (in rev 1.52) to:
- panic("soaccept: !NOFDREF")
- fatal trap 12, with tracebacks going thru soclose and soaccept
Drivers should be updated if they get flagged by this message.
(The reason this is important is because we do not have a way
to catch this mistake for interfaces added after ifinit() runs.)
in vm_map_simplify_entry. Basically, once you've verified that
the objects in the adjacent vm_map_entry's are the same, either
NULL or the same vm_object, there's no point in checking that the
objects have the same behavior.

Increase the overall length of the delay by 10.
Without this a 3C509 card on my MediaGX crash box can't be reliably
read. With this it is solid.
I've left a delay multiplier in instead of just changing the base
delay because I'm surprised I had to increase it so much and expect
there may be another problem.

Fix the following problem:
As the code stands now, growing any stack, and not just the process's
main stack, modifies vm->vm_ssize. This is inconsistent with the code
earlier in the same procedure.

Add a tunable delay at the beginning of the SHUTDOWN_FINAL at_shutdown
queue, allowing time to settle before we launch into the list of things
that are expected to turn the system off.
Fix a bug in at_shutdown_pri() where the second insertion always put
the item in second position in the queue.

Change microseq offsets. Previously, offsets of the program counter where
added to the index of the current microinstruction. Make them rely on the
index of the next executed microinstruction.

Using suser() means that the p_acflag will (can) be set, to show that
a process used super-powers during execution. It also makes it easier
to restrict roots we don't trust later on.

asynchronous events can be handled (e.g., speed negotiation, target mode).

But anyway comment it out and use new SBus 7.55 firmware. We get fast posting
