PQinitOpenSSL also doesn't appear. I'll ask the HDBC maintainer if
he's considered this issue.
As far as connections getting dropped: yes, this sounds reasonable,
but given that both the client and the server are running on the same
machine, will connections (to 127.0.0.1) really be dropped once every
100.000 or so?
