Is it possible to make any exe resident in memory?

For example let's say I need to call开发者_运维问答 curl.exe 1000 times in a row from rebol (see c# httpWebrequest with proxy works but not curl ) to avoid reloading curl from disk each time, is there a way to make it stay in memory ? I don't think making a windows service does that.

No; Windows should be doing that automatically.
