Subject: * cygheap.h (cygheap_fdmanip::isopen): Set appropriate errno if fd
 not open. * select.cc (fhandler_base::ready_for_read): Release an open guard
 mutex when exiting with an error condition. * syscalls.cc (_read): Check
 frequently for closed fd as a kludge until something better is invented.
