You mean an end-user of the application? Or you mean the application 
programmer? 

I'm not sure there is any difference between "user modules" and "library 
modules" apart from what they do.

Perhaps it would help if you could explain the circumstances of when you 
would reload a module. During application development, for an incremental 
edit/reload/test cycle? Or while the completed application is being 
executed?

If the IDE is getting in your way, then don't use it.

Or if you tell us what IDE you're using, and precisely what it is doing, 
somebody can tell you how to defeat the IDE's cache.

(That won't be me -- I don't use IDEs.)

Or perhaps you're entire approach is wrong, and you shouldn't be using 
reload() at all. Don't know.
