 * status:  assigned => needs_review


Comment:

 Option 1:  set the LIBC_FATAL_STDERR_ environment variable.

 Option 2: Have the sandbox respond to unacceptable open(...O_RDWR) to fail
 with an error (EACCES?), rather than crashing tor.

 I think option 1 is better, since it's easier to debug other things when
 O_RDWR still traps with a signal.

 See branch "bug14759" in my public repository for an implementation.
