Hi

I don't remember well, there was maybe similar ToDo.

Yesterday I got a incident on high load system when I executed DROP INDEX cmd.

This statement waited on a finish of long transaction, but it stopped any other statements.

Can be nice when waiting on lock statement doesn't block another statements.

Regards

Pavel
