Comment (by mikeperry):

 Ok I think the first thing to do is to make this be a simple fix that
 prevents us from triggering OOM conditions. The simplest way to do this is
 to inspect the circuitmux queue and if it is too full, just not send the
 padding cell, emit a log, and tell the padding system we did send a
 padding cell. I filed #29494 for optimizing this solution, which we may or
 may not need to do depending on the padding machines we make.
