If the disk has been physically removed, this will cause a very long
hang on accessing the file, and a lot of kernel-level errors within
syslog.  It can take up to several minutes for the kernel to decide that
something is very wrong, and you'll have a syslog that is up to 100k
larger for your troubles.
