This script attempts to reproduce poor glibc allocator behavior within Ruby, leading
to extreme memory fragmentation and process RSS bloat.

glibc allocates memory using per-thread "arenas".  These blocks can easily fragment when
some objects are free'd and others are long-lived.

Our script runs multiple threads, all allocating randomly sized "large" Strings between 4,000
and 40,000 bytes in size.  This simulates Rails views with ERB creating large chunks of HTML
to output to the browser. Some of these strings are kept around and some are discarded.
