My argument for symfs is that $HOME is not relevant or if it is the path 
is symfs/$HOME. The use case is dealing with countless images -- some 
development, some production. I should be able to nuke the symfs when 
the analysis is done and everything related to it is gone. With the 
$HOME/.debug path it just grows on and on with no real means of pruning it.

If the vdsos are for a particular symfs then why aren't the vdso's under 
it in a known location?
