#66 closed defect (fixed)
Regression caused by grid related changes

Description
It seems the recent grid related changes have caused a regression which affects the zoom feature. If some processes have nothing to output, XIOS will deadlock. This can be reproduced using the "test_complete" example after r565.
This is possibly caused by the "pseudo-global" communication style used by XIOS, if one client skips the communication with the server, a deadlock will occur.

This bug relates to the calculation of real connected servers, which a client needs to send the message to. In some cases of zoom, several server tried to listen to "never come" message, which caused deadlock.
This buf is fixed in r584
