I think that's certainly the right start. File a defect with the

   signal handling?

* Was it ever POSIX's intent to allow a signal handler to
   modify the errno of the interrupted code sequence or was
   that simply a consequence of being a signal handler and
   modifying global state?

... and anything else you think we should get an expert opinion
on before embarking upon a change like this.
