Bug #7459

at_exit { Thread.new {} } broken in r37921

Description

ruby -e 'p Thread.current; at_exit { p Thread.current; [Thread.new {}].map(&:join) }'

outputs:

#<Thread:0x007feeb28b0fa8 run>
#<Thread:0x007feeb28b0fa8 dead>
-e:1:in new': can't alloc thread (ThreadError) from -e:1:in block in '

Either the main thread shouldn't be marked as dead until it actually is, or the check in thread_s_new should be expanded to include whatever thread is responsible for the at_exit run.

I don't think main thread should be marked dead until after at_exit is done:

% multiruby -e 'p Thread.current; at_exit { p Thread.current }'

VERSION = mri_trunk
CMD = ~/.multiruby/install/mri_trunk/bin/ruby -e p Thread.current; at_exit { p Thread.current }

This is blocking my merge of minitest to trunk for 2.0 preview.
