History
jhb c3ffedd66b When reopening a stream backed by an open file descriptor, do not close 
the existing file descriptor.  Instead, let dup2() atomically close the
old file descriptor when assigning the newly opened file to the same
descriptor.  This closes a race in a multithreaded application where a
concurrent open() could allocate the existing file descriptor in between
the calls to close() and dup2().
