* Read doc/experiments/hash/results.txt and use the methodology below
* Write benchmarks for Array#sort
* Use a sensible set of Array sizes from 10 to 10,000
* For each size, provide a) random Fixnum values, b) semi-random, c) semi-sorted
* Define what semi-random and semi-sorted mean quantitatively
* Follow the Hash example and generalize the Array rubyspecs to use new_array
* Research and Implement a) bottom-up heap sort, b) mergesort, c) in-place mergesort
* Document the algorithms and the papers referred to
* Run the implementations against the specs
* Run the implementations against the benchmarks for both interpreted only and JIT

Subject: [PATCH] Reworked capi cached handles management.
Handles are persistent references to managed-memory objects (i.e.
"Ruby" objects). Objects that have handles are kept alive either
by the handle having a greater than 0 reference count, or the object
being reachable from another object.

# This script provides a place to insert a potentially platform-specific
# method of monitoring a benchmark and possibly aborting the run if it
# exceeds a specified time limit. See README for more details.
