Add SharedSerializedTaskStore
(double to single quoted string)
Clarify deque num_slots vs max_size
Silence RubyMine warnings due to FFI data access
Remove mutex from SharedDeque -- make it callers responsibility for now
Make task store default to the default sized mem pool
(fix comment)
Whole bunch of spiking: can exec fib(2) on 2 workers
Calculate fib(10) in one worker using threads
(cosmetic -- re-order methods)
Increase default size of deques to 1024
Pick up our proposed fix for ProcessShared::Mutex from git branch
Pick up our proposed fix for PrcessShared::SharedMemoryIO#read from git
  branch
Add default spec_helper.rb (from rspec --init)
Fix dump/load exception through SharedMemoryPool
Add default .rspec (from rspec --init)
Increase default SharedMemoryPool size to 1M -- does fib(17) in 1 worker
Aha! Increasing to 8 workers speeds fib(17) from 19s to 5s
Half size shared mem blocks, twice as many -- does fib(20) in 8 workers
