OTOH, it's looks about the same as in Java and even Java now has
explicit Locks, because synchronized simply isn't efficient nor
flexible enough... ;)
Since I don't use java, what's the difference of locks?

Yes, but often the question is not how long the *locking* operation takes, but
rather how long the *locked* operation takes.
Of course you are right, but this is not a compiler / Library thing but
depends on the design of the user program.

This is an idea using automatic cleanup of interfaces:
procedure foo; - lock
begin
synchronize(cs);
[...]
end; - unlock
or
procedure foo; - lock
begin
with synchronize(cs) do - lock
begin
[...]
end; - unlock
end;
{ TLock }

TLock = class(TInterfacedObject)

It still uses the MultiReads. I have a new version that compiles

I disagree with your definition of what is optimisation, but I accept the

important to the other developers, and I was just making them aware of the
