Subject: [PATCH] Added list to store history of messages. This is done to
 address a memory leak. Each thread allocates another 512 bytes and never
 frees it, but the program breaks if it is freed. Storing a copy of the
 messages in this list will allow each message stored to be trimmed to its
 actual size and not 512 bytes, and then the original message can be freed. At
 the end of execution, the list can be freed.
