Comment (by arma):

 Replying to [comment:23 arma]:
 > And for the NTor expected delay, we should now expect it to be the delay
 from queued NTor cells, plus the delay for the fraction
 1/num_ntors_per_tap of the queued tap cells, assuming there are that many
 queued.

 See git commit 533adef1d:
 {{{
     Be more general in calculating expected onion queue processing time

     Now we consider the TAP cells we'll process while draining the NTor
     queue, and vice versa.
 }}}

 I think for the upcoming cases we expect to see in the wild, it does
 simplify to "refuse a lot of tap requests if there are many ntor
 requests". And I'm ok with that.
