Hi,
Unless I'm mistaken or there's some weird coincidence, running the above
command on my VPS actually appears to generate extra entropy.
Here's a graph of my VM's entropy:

I'm guessing I'm one of the ones who could well benefit from hooking
upto the new entropy key. (It's a standard debian stable system,
2.6.26-2-xen-686 kernel.)

If you're on IRC, or follow me/bitfolk on
twitter or on Facebook
you're probably bored to tears hearing about this, but just in case
there's some of you who aren't..
I've been investigating the issue of lack of entropy in virtual
machines recently, and have gone into it in some detail in the
following two blog postings:

Thanks for this Andy!
I've been running
watch -n 0.25 cat /proc/sys/kernel/random/entropy_avail
...as recommended buy Hugo in the comments and my VPS fills up with
entropy very quickly.
