[s2;%% Lightweight busywaiting synchronization lock. Unlike Mutex,
SpinLock waits in a loop until resource becomes available, thus
avoiding costs of system call at the price of active wating.
SpinLock methods are also usually inlined (and trivial). SpinLock
is [* not] reentrant and also [* not] fair (if more threads are waiting
on the same SpinLock, the order of acquiring it is not specified).&]
