Properly protect player struct with mutex
The volatile keyword neither guarantees atomic access nor memory visibility[1]. Although this is usually not a problem on x86, it is incorrect to rely on this. Use mutex locks to protect all shared player variables and enforce memory visibility. [1] https://wiki.sei.cmu.edu/confluence/display/c/CON02-C.+Do+not+use+volatile+as+a+synchronization+primitive
