Task Description: The Parrot source code file src/misc.c contains a number of utility functions which the rest of the Parrot source code uses for various purposes. Because the code in this file has no common theme and because these routines are used throughout Parrot, it's important that it be fully tested.

Write tests to bring test coverage for this file up to 100%.

Steps to Complete:

1. Create a fork of parrot/parrot on Github
2. Add tests necessary to bring the coverage up to 100%. Add these tests wherever is appropriate.
3. Open a pull request on Github
