Well... It's hard to test, as Imagestream FR driver doesn't work for me.
This memory leak is critical - I have sent (some sort of) patch
to Imagestream few weeks ago which should fix it. However, writing
a patch for a code I can't see is not an easy job.

Anyway, old SDL driver works (with problems less critical than the memory
leak) - I've fixed the leak as SDL published (this) source file.

But it was fixable in SDL driver, and Imagestream's one is binary-only.
BTW: Is that true that the drivers contain GPLed code, namely from
Linux' drivers/net/skeleton.c?

Thanks for info. I will ask
