I don't know if this behaviour is typical across operating systems, but it's frustrating to find yourself locked out a server just because a single process went to town on the i/o subsystem.

that privileged SSH process should be spawned on RAM disk to avoid being 
caught up by I/O problems.

Another solution would be to have core root directory (no var/log's and 
similar) in RAM disk (either as cache or duplicated files) so important 
processes are independent from I/O problems.

Or maybe having that core root tree on separate HDD and separate HDD 
controller.
