Hi,

Just an idea.

How about to add try_pop?

How

about to implement Queue#to_a method that generate array which
contains queues containing objects?


# I agree the name Thread::Queue because it is clear

# Simple Queue class is ambiguous that we can use it

# ::Queue is familiar as a data for synchronization.
