install directories in modules RC

Shall all the installed modules have the install directories deleted after successful installation?

Just popped into this issue by coincidence when I checked flash application and found out that "wall" application was not installed. I got a message to delete install directory from this app.

I did delete the main install directory after I installed it, but didn't know about module's install directory

DO NOT delete the install directory for the modules. This directory is there because you can install or uninstall this module anytime you choose. If the install directory is deleted, if you ever uninstalled the "wall" you could never add it back.
