[issue10478] Ctrl-C locks up the interpreter

[STINNER Victor]

Ok, so +1 to apply immediatly your patch which "fixes" the deadlock. If someone is motived to make Buffered* classes reentrant, (s)he can remove this exception.

io and signal documentation should also be improved to indicate that using buffered I/O in a signal handler may raise a RuntimeError on reentrant call (and give an example to explain the problem?).

About the patch: can't you move "&& (self->owner = PyThread_get_thread_ident(), 1) )" in _enter_buffered_busy()?
