Thank you for explanation, but frankly speaking, I have no interest
about how my software works under windows.
I even havent' thought that windows has mmap =)

It will be ok for me just to have instruments to implement
functionality, that works under Linux, OS X and FreeBSD: I've never
met with anything else.

Not exactly so: hard disk space will be still used, so problem is not
with ability to delete,
problem is in deterministic deletion of file. I understand this risk
and it is ok, because speed matters more, than
delay in deletion of file.
