Donal: 

Great! I had seen many reports about memory usage, some in the use of
markers, and had not had time to look into it. I will open a ticket and
make sure that this gets looked at for addition in 2.4. If you want to
create a patch of your differences between SVN and your changed version,
and add it to:
 
  http://trac.openlayers.org/ticket/369

that would be great.

(This is probably having a huge affect on some of the applications that
I am personally interested in, so I'm looking forward to getting this
fix in.)
