NetBSD recently reworked their disk buffer system. They then added a new
strategy option which improves the response time of the system by giving
more priority to reads. I ported it to OpenBSD. It works quite well.
Compiling without the new strategy should be equivalent to the current
system, just with the code moved around. The new option makes things a
tiny bit slower, but improves "feel".

Where's Reagan? Gone after two! Defeated by George Bush and
Michael Dukakis no less."
