Re: ZwCloseHandle asynchronous on no read/write activity?



I think the FS should queue the request, ie internally delay the
actual processing of the close/cleanup IRP even with STATUS_SUCCESS
return.

and "delete-on-close" should be delayed too.

I believe this is both true for NTFS & FAT.

but this should be properly documented like it is done for other OSes.

micro optimizing one call, you can't fully peg the CPU in all paths

why not, it does not take much time anyway. :)
