In the not-multithreaded version. In the multithreaded version 
you would have to use a heap allocated object that does not move 
and put the mutex there.

If std.move(x) wipes out x, without checking mutexes first... 
well, that can't work well with multi-threading. I guess you 
could avoid using std.move(x) and use a different function, but 
how do you ensure that?
