Comment(by joshua.balla...@…):
A day of Yak shaving later, and it seems that the root cause is calling
"invalidate_method_cache" as part of method resolution when another thread
already has the cached method in use. As suggested by Laurent, first
calling the methods once on the main thread fixes the issue:
{{{
class Foo
def doit
puts "hi there!"
end
end
class Bar
def initialize
@foo = Foo.new
end
def step
100.times{ @foo.doit }
end
end
@bars = []
1000.times { @bars << Bar.new }
@bars.each(&:step)
steps = Dispatch::Group.new
@bars.each do |bar|
Dispatch::Queue.concurrent.async(steps) { bar.step }
end
steps.wait
}}}
