Bug #4237: SSL_shutdown should be called until it returns 0
http://redmine.ruby-lang.org/issues/show/4237

Author: Aaron Patterson
Status: Open, Priority: Normal

The documentation says SSL_shutdown should be called until it returns 0.  I believe this was causing heap corruption that can be demonstrated through the steps listed here:

make sure you use Ruby r30293 or earlier.  I believe r30294 only fixed a symptom is it closes the SSL socket twice (once from the call to `close` and once again during GC).

Please note that Sam sees the problem because postfix is establishing a TLS connection.
