Deepak - thanks for the simple and valid idea, please allow me to explain
what I need and done from scratch.

My load test script looks like:
+Test Plan
++Authenticated View Blogs (thread group)
+++Once only controller
++++Login (Include controller)
+++View Blog (Include controller)
+++Throughput controller (re-login only sometimes)
++++Login (Include controller)

++Anonymous View Blogs (thread group)
+++View Blog (Include controller)
+++Throughput controller (drop session only sometimes)
++++Drop anonymous session (and all cookies)   <--- not yet implemented
.
.
.
(total of ~40 thread groups)


Login.jmx (which is used above) looks like:
+Login (http sampler)
++pre processor to drop all cookie


Now, I need to sometimes drop sessions for anonymous threads as well.
With the idea from Deepak I've added post processor, which save the
cookieManager into a vars, and placed this post processor in the root of my
main Test Plan above.
Utilizing the fact that post processors are applied to samplers fetched
using the Include Controller, I now have the cookieManager available for
any thread at any time in the vars.

I'm giving that a first try now with real load test, but I don't expect
having multiple references to the CookieManager break anything...

Thanks for the help.
