The module manager knows what modules have been loaded, but it doesn't
provide an iterator.
If you know the URLs, you can check a given module's load status. It is
harmless (other than creating some cached state) to probe a given URL
before you call "load".
Removing the tab (and ensuring that you have no other references to the
child control) will only cause instance data to be GC'ed, not the
underlying bytecode.
The module's code will never get fully recycled unless you call
"unload", because there is a ModuleInfo reference handing onto its
internal module class factory (in case there is a subsequent need to
reuse it).

Roger, thank you for your quick response.
Does the module factory hold information (module ID, URL etc...)
about the modules I have loaded?
How important is it to unload modules? If I remove a specific
tab
from the navigator will GC eventually clean up the child module
on
that tab?
