In PVM, when one sends 2 messages from task A to task B, and task B does
a receive with a wildcard, than the first message that is send will be
received.

But what when 2 tasks (say A and B) send a message to task C and C does
a receive with an wildcard. Will it receive the message that arrived
first or is it not possible to tell?

If not, how can one be sure that when e.g. A keeps sending messages, a
message send by B will not be 'pushed away' for ever? (This is a kind of
fairnes)

Unfortunately I couldn't find any info about this on the pvm websites.

Thanx in advance,
