#664: MacRuby Crashes When Scheduling a Block to Run on the Main Thread from a
Background Thread

Comment(by lsansone...@…):
Proc#call is currently not directly callable from C/ObjC. Can you try this
workaround instead:
{{{
def main_thread( &block )
o = Object.new
def o.call
@block.call
end
o.instance_variable_set(:@block, block)
o.performSelectorOnMainThread( 'call', withObject: nil, waitUntilDone:
true )
end
Thread.new do
main_thread do
[1,2,3].each {|i| puts i }
end
end
}}}
