I'm having some problem with nonblocking p2p communications. This is with boost 1.47 and openmpi-1.5.3 compiled with icpc 12.0.3.
I tried to run your example on my Ubuntu 11.04 box (GCC 4.5.2, OpenMPI
1.4.3, both coming from the main Ubuntu packages) and get no error:

Task 1 posting recv from 0
Task 0 sending to 1
Task 1 sending to 0

Task 0 posting recv from 2
Task 0 sending to 2
Task 1 posting recv from 2
Task 1 sending to 2
Task 1 received message tag 13 from task 0
Task 2 received message tag 13 from task 1
Task 1 received message tag 13 from task 2

"handshake_reqs_". If I substitute it with the following, all
messages are received correctly:
// receive all messages in final loop
while (not handshake_reqs_.empty()) {
int i = 0;
while(i
