The commit prevented CRLR, but did not address an isolated CR or an
isolated LF.

Loop with String#scan without creating substrings

rest of the buffer.  Also removed a useless, probable typo, regexp.

	handle_interrupt to defend monitor state [Bug #15992]

	If an exception is raised from another thread for example Timeout
	and this thread is just after `mon_exit`'s `@mon_owner = nil`,
	the exception breaks the state of MonitorMixin. To prevent that situation,
	it need to block interruption in mon_enter and mon_exit.

	Avoid creating Hash objects per each mon_synchronize call (#2393)
