           Summary: Extreme memory usage when `synchronized( object )` is

Example code

On DMD 2.067.1, when `synchronized` keyword is used with a parameter that is
`this` or just another shared object, memory consumption increases
continuously.

I am informed that on DMD 2.066.0, this is not the case, and it doesn't
increase memory consumption.

As seen in the example file, if object is destroyed by using `destroy`
function, even the `synchronized` is used with an object, memory usage is still
stable.
