SSL module indexing the NULL-value
Imported from http://bugzilla.roxen.com/bugzilla/show_bug.cgi?id=1704
Reported by Pär Svensson, Roxen IS noy@lysator.liu.se
In some circumstances the SSL module is trying to do a write() on a stdio.File object that is NULL. The behavior is observed to happend in blocking mode. Probably just some more errorchecking is needed in sslfile.pike.
