Making HTTP POST requests to an Apache server over HTTPS frequently fails on OS
X due to TlsExceptions.

Reproducible: Always

Steps to Reproduce:
Please use "make run" to run attached sample application. Application will
attempt to make 1000 requests. On my system, a TlsException is thrown within
the first 100 requests every time.


Expected Results:
Running the same sample on 2.6.7 Linux does not produce TlsExceptions.

I have observed this "Bad record MAC" as well when using a TLS connection to a
Tigase XMPP server. The issue only occurs on a multiprocessor/multicore
machine when handling many XMPP requests.

We have replaced the SSL stack in Mono with BoringSSL, this should no longer be
an issue
