Comment (by nickm):

 Branch "bug10169_023" is a very hurried implementation of an approximation
 of this.

 What it is missing is:
   * it needs to aggressively free the bytes in the buffers rather than
 just marking the connections, to free up RAM faster.
   * it needs to count the bytes in the buffers as it's removing them, to
 know when it's freed 10% of the total allocations here.
   * probably something else; I'm in a hurry
