Please log in for more thread options however in this case, the messages are sent in a range which is explicitely
reserved for private use by the application.
since the OS (that includes the shell and proprietary drivers) on various
devices (Samsung i-600, Motorola Q, and others) send messages in the private
range normally reserved for the inside use by applications (for inter-thread
communication), it is very difficult for application to determine for sure
what range of messages can be safely used for its own inter-thread
communications.
