Checklist of areas likely requiring validatation of thread safety.

Global variables in the BSS and Data segments which must be reviewed to see if they require any protection in a threaded environment.

NOTE: After implementing thread protection on one of these, or determining that it doesn't require any changes, move the entry into the "Already Reviewed" section at the bottom of this page, and make a note of your specific findings or work done.
