sad to see, that

synchronized

will go away from common (

Synchronization on any object is not supported on every platform and will be removed from the common standard library soon.

). Is there another locking mechanism available?

I've had to use Mutex before on a few occasions.

hm... is there no alternative in the stdlib?

I'm not entirely sure.

There’s a locks package in the atomicfu library which provides multiplatform synchronized and ReentrantLock, as far as I can tell
