Looked into this a while ago. Bottom line was you can never guarantee
an unload, so repeated load/unload always have the potential for
memory leaks.
In the case of Flex apps it was never possible to completely clear
them from memory.
Our solution was to load other swfs in another window, though I
appreciate this won't suit everyone. It may be possibleto load them on
the same page with JavaScript communication between apps. If there is
a physical overlap between the display areas, eg using z-index of CSS
you may give up the option of 3d acceleration in flash 11 and there
may be issues with display on some operating systems/ browsers
On my phone now, but I can give links if you're interested
