 =head1 DESCRIPTION
 
 Extremely similar to open2(), open3() spawns the given $cmd and
-connects RDRFH for reading, WTRFH for writing, and ERRFH for errors.  If
-ERRFH is false, or the same file descriptor as RDRFH, then STDOUT and 
-STDERR of the child are on the same filehandle.  The WTRFH will have
-autoflush turned on.

 If either reader or writer is the null string, this will be replaced
 by an autogenerated filehandle.  If so, you must pass a valid lvalue
