With respect, what you and the OP are seeing happens to be one of the primary
manifestations of BLODA.  Please show that you have ruled that out as a
possible cause; after that we can consider other explanations.

For example, run 'cygcheck -svr' and post its output, *as an attachment*, in
a followup post.  cygcheck checks for evidence of BLODA installations and is
the first step towards ruling out this possibility.  You could also visually
scan the list of apps in the link I posted earlier in this thread, just to
make sure you don't have one of these dodgy apps installed.

I believe my first problem report to this list several years ago was this
very observation about increasing virtual memory consumption for no good reason.
 In my case it was BLODA, an anti-virus program that I was luckily
able to configure to not scan the Cygwin installation tree.
HTH,
