* #30014: make selectors.DefaultSelector.modify() faster by relying on selector's modify() method instead of un/register()ing the fd
* #30014: add unit test
* speedup poll/epoll/devpoll modify() method by using internal modify() call
* update doc
* address PR comments
* update NEWS entries
* use != instead of 'is not'
Selector.select() is now retried with the recomputed timeout when interrupted
by a signal.
Write an unit test with a signal handler raising an exception, and a unit with
a signal handler which does not raise an exception (it does nothing).
RuntimeError if the selector is closed. And selectors.BaseSelector.close() now
clears its internal reference to the selector mapping to break a reference
cycle. Initial patch written by Martin Richard.
threading.Lock.acquire(), threading.RLock.acquire() and socket operations now
use a monotonic clock, instead of the system clock, when a timeout is used.
zero, instead of rounding towards zero. For example, a timeout of one
microsecond is now rounded to one millisecond, instead of being rounded to
zero.
Move also a test in test_epoll which was moved by my previous merge.
the unit test on max time (but be more strict on mon time). Example of failure:
