Comment (by Roland Haas):

 I have to see how to actually make this change in the Kranc source. What
 one needs is a {{{SYNC: ML_Gamma}}} to ML_BSSN's schedule block for
 {{{ML_BSSN_InitialADMBase2Interior}}}. Suggestions on how to achieve this
 best would be very welcome.

 In theory as {{{SYNC}}} should always be harmless. I will run the BBH
 gallery example for a bit to make sure though. I have checked (before even
 creating the ticket) that adding the SYNC lets me run the previously
 failing parfile (which has no multipatch and no mesh refinement so is far
 from a production) without failures.
