Slow "Dismount All" Performance

The "Dismount All" option takes a rather long time (30-60 seconds). It doesn't seem to be a problem with the dismount function in general (dismounting an individual volume is almost immediate).

EDIT: The problem cleared up later, with "Dismount All" becoming almost instantaneous. I haven't been able to replicate the issue; I suspect some other process was accessing one of the VeraCrypt disks and was causing a delay as it shut down (which would be an extraneous issue).

Thank for the update.
The time taken to dismount a volume depends on Windows. Sometimes, there maybe data in Windows cache pending to be written and so the dismount call doesn't return before all data have been written. From VeraCrypt point of view, dismounting is just a combination of few system calls.
