Comment (by Vort):

 > Then again, is that true for outbound connection too? Or only incoming
 connections broken?

 This test requires complete rewrite (and port) of BwTest.
 And I'm not sure that this test reproduces the problem with 100% accuracy.
 So maybe I will do this, but not right now.

 Another thought:
 Right now I am running the relay with ~1100 established connections.
 It is official 0.3.0.8 build with `ConstrainedSockSize 262144` tweak.
 But I don't see where are the wasted 262144 * 2 * 1100 = 550 MiB are
 located.
 tor.exe have only 118 MiB of "Private Bytes" and 259 MiB of "Virtual Size"
 used.
 Not much higher than freshly started tor.exe process uses: 55 MiB and 161
 MiB respectively.
