While solving bug 3780, I left behind some code that tries to clean up ~/.thinlinc/xinit.log, just to make sure there aren't stray links still in that directory. We should probably stop doing that some time in the future. This bug is sponsored by the I-can't-remember-anything-unless-it's-in-Bugzilla corporation and the For-Completeness-Sake Initiative.
Solved by r28292.
Review code and it looks good.
