/// This call will block while waiting for the source to send a process destroy

/// main() function from exiting until it is directed to by the source. When
/// the shutdown message is received this function will stop any future run
/// functions from executing but will wait for any current run functions to
/// complete. All Intel® Coprocessor Offload Infrastructure (Intel® COI)  resources will be cleaned up and no additional Intel® Coprocessor Offload Infrastructure (Intel® COI)  APIs
/// should be called after this function returns.  This function does not
/// invoke exit() so the application can perform any of its own cleanup once

/// Note that having an additional thread printing forever while another
/// calls COIProxyFlush may lead to a hang because the process will be forced
/// to wait until all that output can be flushed to the source before returning
/// from this call.
