Subject: merge revision(s) 63741: [Backport #14868]

	process.c (ruby_fork_ruby): fix race in signal handling

	We must block signals before stopping timer-thread, otherwise
	signal handing may be delayed until (and if) another signal
	is received after timer-thread is restarted.

	[ruby-core:87622] [Bug #14868] [Bug #13916]
