Now that I think about it, there will still be a race condition with my patch
applied.. since I did not think about the first if failing when it checks for
equality and then failing upon checking for NULL, in which case the same
context could be inserted multiple times at different positions.

It would seem the find_context function requires a fast mutex lock anyway. So
the fix would be to keep the old code and put the lock around the original for
loop.
