Igor,
Granted. That is why I built this script to do the mount only ONCE for all
running instances. So when I start a second or subsequently cygwin session,
I do NOT attempt to mount again, thus affecting things globally - I ran
into that problem inadvertently without realising it. Once I caught on to
this, I came up with a method to store info in the Windows registry
regarding the number of running instances, but this approach was
problematic. That is when I came up with the below.
I am using this method very successfully here at work and at home. I just
wanted to pass on my tip.

Alan,
FYI, once you change the mount table, you change it globally for all
running instances.
