Work Description: Github user oknet commented on the issue:
https://github.com/apache/trafficserver/pull/823
@jpeach SessionAccept is a interface to create ClientSession. Its mutex is
NULL, it is not safe to release any resource. The caller to SessionAccept is
Trampline that mutex is copy from NetVC, it is safe to handle resource release.
This is why I'm free MIOBuffer in Trampline.
