"Fix SEGV in Ruby 2.4" is not published

#6 is not published.
It causes SEGV on rrrspec local tests.

irb(main):001:0> require 'extreme_timeout'; ExtremeTimeout::timeout(1) { sleep (2) }

[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

Timeout thread is left if the block given is escaped by an exception

Use rb_protect and ready for exceptions.

ExtremeTimeout exits while GC is working

Object allocation while GC is prohibited, and ExtremeTimeout is allocating some objects while its exiting procedure. Thus, timeout with GC working leads an abnormal exit of ruby.

Make ExtremeTimeout to wait GC.
