# Using STM

Create a custom implementation of some data structure.  Data structure
should work according to its definition,
follow the Big-O limitations,  
be completely thread-safe in concurrent environment and use only STM
primitives in implementation.

You are free to use any Java STM library, but we recommend
[Multiverse STM](http://multiverse.codehaus.org/overview.html)
