Hi,

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 "get wrong"?

Proposition

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.
