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.

Duh... check that malloc() hasn't returned a NULL *before* we zero the buffer,
...
not after. Pointed out by Michael Graff.

Try a bit harder to detect the physical failure of a component, and to
...
mark that component as dead. Physical failures are handled much better now.

If a configuration fails due to a non-existant spare, remember to release
...
any previously allocated components before bailing. Credit to Manuel Bouyer
for noticing this.
