<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Due to the tireless efforts of Thomas Arimont, two sources memory leaks in TLS have been discovered. These are:
* Improper initialization (and multiple re-initializations) of portions of the SSL library. You should only need to call SSL_library_init() and SSL_load_error_strings() once; OpenSSL_add_all_algorithms is already accounted for by SSL_library_init, and SSL_load_crypto_strings is already accounted for by SSL_load_error_strings. This action was happening multiple times as well when setting up an SSL session.
* Failure to completely clean up after a TLS client. This included not clearing the error stack when the TLS client thread exited, and not disposing of the SSL_CTX object when the TLS client was finished.
This patch resolves both memory leaks, and removes some sleep(2) calls in off nominal paths.</pre>
