Common Problems

Using one thread to send a message and another to process a message is a common technique. However, use care when destroying a message with tt_message_destroy() when another thread might be examining and processing the message contents. This typically results in a program crash when the receiving thread tries to access storage that was freed by another thread. This is the same as managing non-ToolTalk storage in multi-threaded applications, but easier to do using the ToolTalk API.
