Mutlithreaded applications

Some of Tropo's scripting languages, like Ruby, include native support for threads. Tropo functions are not tested with multithreaded application code, and using multiple threads in a Tropo app is unsupported. If your application uses threads, you may experience unpredictable behavior.

Applications that use threading can often cause system resource problems due to leaking threads or poor thread design. To protect Tropo services, applications that use threads and cause these sort of issues may be disabled without prior notice.
