- Added some basic flow control to limit number of posted sends. - Merged endpoint send/recv lock into single endpoint lock. - Set the LMR triplet length in the send path, not at allocation time. This has to be done because upper layers might send less than the amount allocated. - Alter the tie-breaker if statement protecting the second call to dat_ep_connect(). The logic was reversed compared to the tie- breaker for the first dat_ep_connect(), making it possible for 3 or more processes to form a deadlock loop. - Some asserts were added for debugging purposes.. leaving them in place for now. This commit was SVN r10317.
