Comment (by dgoulet):

 To summarize arma, we should get this in, keep the current default in the
 code as is but use a much larger one network wide (consensus). But also,
 you seem to be suggesting that it would be useful for relay operator to
 maybe control that value somehow which means it needs to become also a
 possible torrc option? (the patch doesn't have that).

 50k cells is ~25MB so very little. Going to 50MB for 100k cells. I've seen
 8001 cells *once* on my fast relay in the last 7 days so 50k cells.
