My patches may help with this, but they are a lot more than just a single
change, they are an overhaul of the interrupt threads code. :)  If you are
really curious, you can find them at
http://www.FreeBSD.org/~jhb/patches/sys.patch.  Currently, however, they reduce
the system to a crawl.  Well, at least console I/O feels like a 2400 baud
modem.  I'm even losing characters on the keyboard. :(
