They are * Send, Receive, RMA, User, Persistent * In addition, send and RMA requests may be "incomplete"; this means that * they have not sent their initial packet, and they may store additional * data about the operation that will be used when the initial packet * can be sent. * * Also, requests that are used internally within blocking MPI routines * (only Send and Receive requests) do not require references to * (or increments of the reference counts) communicators or datatypes. * Thus, freeing these requests also does not require testing or * decrementing these fields. * * Finally, we want to avoid multiple tests for a failure to allocate * a request. Thus, the request allocation macros will jump to fn_fail * if there is an error.
