One reason may be that in a good design, the way such exceptions are
handled depends on the frequency with which they occur.

Nobody's arguing that it doesn't have to be handled correctly, but
choosing an optimum way to handle it is easier if you know how often
and under what circumstances it happens. If it happens on 80% of
write() calls you handle it entirely diffently if it happens once or
twice a decand and only when you've received a signal during the
write().
