• lock/{1,2} — wait for release of resource, then lock it (sync);
• trylock/1 — tries to lock the resource; fails if the resource is already locked;
• islocked/1 — returns true if the resource is locked by caller process, otherwise return false;
• withlock/2 — executes a given function under captured lock;
• lend/2 — if process-executor have captured lock, lend tries to pass ownership of locked resource to another process, which is identified by given PID.
