       Test::Trap::Builder::SystemSafe - "Safe" output layer backend using File::Temp


       Version 0.2.1


       This module provides an implementation systemsafe, based on File::Temp, for the trap's
       output layers.  This implementation insists on reopening the output file handles with the
       same descriptors, and therefore, unlike Test::Trap::Builder::TempFile and
       Test::Trap::Builder::PerlIO, is able to trap output from forked-off processes, including

       See also Test::Trap (:stdout and :stderr) and Test::Trap::Builder (output_layer).


       Using File::Temp, we need privileges to create tempfiles.

       We need disk space for the output of every trap (it should clean up after the trap is

       Disk access may be slow -- certainly compared to the in-memory files of PerlIO.

       If the file handle we try to trap using this backend is on an in-memory file, it would not
       be availible to other processes in any case.  Rather than change the semantics of the
       trapped code or silently fail to trap output from forked-off processes, we just raise an
       exception in this case.

       If there is another file handle with the same descriptor (f ex after an "open OTHER,
       '>&=', THIS"), we can't get that file descriptor.  Rather than silently fail, we again
       raise an exception.

       Threads?  No idea.  It might even work correctly.
