--- Comment #27 from Dominic <fdo-bugs.aspseka at xoxy.net> ---
Was not able to trigger any crashes so far. Memory footprint drops as soon as I
stop selecting/deselecting text.

However, I was able to trigger oom condition by *not* stopping ( (de)selecting
every 2-3s or so on my machine is enough to keep Xorg busy on his CPU core and
eating more and more objects.) After about 65k objects, using a tad more than
4GiB, it starts freeing.

I collected a huge log containing two "garbage collections", terminating xorg
via sysreq as soon as I saw the second one happening.
I'll try to attach the last 1M lines of it.
