Question about Varnish Purge

[.]

Hi,

I use the Varnish purge command quite heavily (through this ruby gem:
http://github.com/schoefmax/klarlack), and I heard that there is a bug with
the way Varnish handles it's purge list.

I heard that the purge list is never actually cleared, and can grow to be
really large over time. I use the purge quite a bit (which looks something
like: purge ^/users).

I searched the tickets, and didn't see any mention of this, so I was
wondering if this is even an issue?

Thanks.
