When we have 3 members A,B,C and invoke a blocking RPC, if a member does both receive a valid response and is suspected, both events count twice, e.g.:
A: received / non-suspected (1)
B: received / suspected (2) // wrong, should count as 1 !
C: non-received / non-suspected (0)

So instead of blocking the caller until C is suspected, or we get a valid response from C, the caller in unblocked because we count the valid response and the suspicion of B twice !

This leads to premature termination of a blocking RPC !
