stp Committers,
Oisin Hurley has expired the commit rights for Tony Chau (tchau).  The
reason for this change is:

Tony was a committer on the project, but the relevant project component has
been retired. As such, I'm removing him as inactive according to Dev
Process section 4.7  : http://tinyurl.com/5dyxoo
