It's not stupid, unless the function isn't allowed to throw any
exceptions in standard environments.  See
http://article.gmane.org/gmane.comp.lang.c%2B%2B.pthreads/28

Functions like read() which the C++ standard allows to throw, but
which in practice never do, run a close second in stupidity if you
throw cancellation from them.
