HI ALL:
   Is it ok to introduce USE=dmalloc global flag? description as following
"dmalloc - Enable debugging with the dmalloc library"

current consumers:
 1) net-fs/autofs
 2) net-misc/directvnc
 3) sci-biology/yass

also
 4) app-admin/conserver
 5) net-nds/ypbind
 6) net-fs/samba
 7) net-analyzer/scli
 8) net-analyzer/traceproto
 6) net-misc/siproxd

use dmalloc but controlled under USE=debug

Questions for clarity:

1. I haven't used dmalloc before, what does this use flag do for me?
2. How does this use flag change the built binaries? does it:
   a) make no user visible changes, but adds code instrumentation paths which can only be seen/understood with a special visualiser
   b) add output to TTY for the built binary? etc.

I'm not arguing against global USE for it, I'm just asking for a USE description that is more meaningful.

ie, alternatives might be: "Add runtime debug output via the dmalloc library" or "Add runtime instrumentation for the dmalloc debugger", or something like that.

Because if it were case a), then I might be inclined to turn it on arbitrarily ( depending on how much it impacts performance ), just in case I happen to need it one day.  But if it were case b), I'd be inclined not to turn it on arbitrarily, because I can see that would be irritating =)
