[New-bugs-announce] [issue12462] time.sleep(1): call PyErr_CheckSignals() if the sleep was interrupted

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

While reading floatsleep() (time.sleep) code for issue #12459, I noticed that the Python signal handler is not called in floatsleep() if a signal interrupted the sleep. Well, it just "works" because the bytecode evaluation loop will call PyErr_CheckSignals() before executing the next instruction (the C signal handler signals calls Py_AddPendingCall whichs signals that the pending call to the eval loop using "eval_breaker"), but it would be better to call it directly.

Attached calls explicitly and immediatly PyErr_CheckSignals() in the sleep and Windows implementations of floatsleep().

It's not really a bug, so I prefer to not touch Python 2.7 and 3.2, only Python 3.3.
