Comment:

 Merged the websocketconn fix in [https://gitweb.torproject.org/pluggable-
 transports/snowflake.git/commit/?id=380b133155ad725126bc418d0e66b3c550b4c555
 380b133155ad725126bc418d0e66b3c550b4c555].

 Deployed that version at 2020-02-18 23:18:10.

 Now let's watch it to see if memory use increases from some other cause,
 or remains stable. Here's a graph of memory use today. It was very high
 until being restarted at 19:15 in comment:4, then started creeping up
 again at a rate of about 24 MB / hour (which works out to 1.75 GB in 6.4
 days, about the one week noted in the ticket description). I'll update the
 ticket later with an updated graph when the patched server has been able
 to run for a while.
