Connection closed

Got the following error on a log-running program that sporadically uses the http connection:

Probably related to #89

Start with pkg-http/connection.toit at the set_option call shown in the trace, then read pkg-http/client.toit around try_to_reuse_ and post_. Compare the failure with issue #89 and reproduce it in a long-running program that intermittently uses the HTTP connection. Done should include a confirmed relationship or diagnosis and a verified resolution.
