I was contemplating adding an optional memory-scrubber to ensure that 
we're not doing that: just writing 0xdeadbeef to the ep_ and se_ alloc'd 
memory when we free it.
I was thinking the same thing ....

My first try (just clearing memory) a day or so ago seemed to cause Wireshark to run rather slowly.
I put it aside and didn't delve into why...

Bug in my code ???

Clearing 10 Megs for each frame ??

I think it would be a useful thing to do (at least under a "debug..."
env variable).

I don't think my fixes at this point will involve
emem.c so feel free .  :)
