No other ill effects noticed. Perfomance is bearable. The default on Cygwin is now NO_MMAP. I've disabled that default in my own Cygwin environment and continue to use mmap() rather than pread(), but I'm also running my sp/mmap change there. I haven't noticed a performance difference, but I also haven't tested for one. IOW if there is a difference its close enough to noise to not be visible to me as a user. -- Shawn.
