        src/sys/dev/raidframe: rf_desc.h rf_driver.c rf_netbsdkintf.c
            rf_states.c
Log Message:
Make it so raidframe will only perform synchronous writes, and async
reads.  This avoids a problem where many writes will cause the driver
to allocate way too much memory.

This needs to change to a queueing system later, which will provide a
way to limit the memory consumed by the driver.

Without these changes, raidframe would use 24M or more on my machine when
the buffer cache dumped all its dirty blocks.  Now it uses around 200k
or so.
