  Log:
  Bugfix:
  The sync-call before the for loop is premature. For at this time the connection to the server has not been accepted. Hence, the sync-call catches a timeout-error message. Unfortunately this takes 20s. So the client will be set up with a delay of 20s. Calls to maxima in this timeslot might lead (and do in practice) to "code ran too long" errors in the calling problem.
  
  Moving the said sync-call after the $server-accept command remedies this issue.
