Sorry but I don't understand your remark. What is your problem with
retrying syscall on EINTR? Can you please elaborate? What do you mean by

> > If a system call fails with ``EINTR``, Python must call signal
> > handlers: call ``PyErr_CheckSignals()``. If a signal handler raises
> > an exception, the Python function fails with the exception.
> > Otherwise, the system call is retried. If the system call takes a
> > timeout parameter, the timeout is recomputed.
> Signals are tricky and easy to get wrong, to be sure, but I think it is
> dangerous for Python to unconditionally commandeer signal handling. If
> the proposition is accepted, there should be a way to opt out.
