I'll look when I can, but since you mentioned "there's obviously some room
for optimization", could you state the obvious as a lead for someone who
has th
? Would it then only penalize deletes of open files?
(Incidentally, I've noticed this as well.)

Note also that we usually run with /3GB /Userva=2800, which means 1.2G
kernel/2.8G application, because we found that certain drivers need that
much kernel space to map their large PCI memories (video cards, image
processing boards, SCSI drivers, etc.)

Posix symantics: mmap fixed region x, mmap fixed region y which is a
subregion of x where y replaces x's mapping.

I don't know what mmap magic Cygwin uses internally to do this, but can't
you just map the big region, then overmap the disk file without the map,
unmap, remap, remap?

uld this change be (for disk files, raw devices,
mail slots, etc.) (memory devices already use 64k for st_blksize)?

Or, to add a messy but sometimes useful option not previously directly
mentioned in this thread, use the same C++ compiler as was used to
generate this library to create an extern C wrapper API. The C wrapper
API
Just FYI for now in case anyone is interested enough to look. I'll try
and make an STC, and possibly a patch when I have time to look further.
Thanks.
