Ian Griffiths comes up with an interesting way to use IDisposable and the “using“ statement to get a very of lock with timeout.
I like the approach, but there are two ways to improve it:
1) Define TimedLock as a struct instead of a class, so that there’s no heap allocation involved.
2) Implement Dispose() with a public implementation rather than a private one. If that’s the case, the compiler will call Dispose() directly, otherwise it will box to the IDisposable interface before calling Dispose().
