I use  a subject line with something which is not related to to the
message like "Beer or Wine" or "Eat potatoes".  This way you can
easily figure out to which thread a message belongs but you are not
giving away any information.  There may be an interconnection
somewhere deep in the brain and psychologists may find a way to deduce
some information from the subject line.  I think this is a much lower
risk than all the information you can get from traffic analysis.

If you want to encrypt the subject you should use MIME and encrypt an
entire message as an rfc822 attachment.
