thank you for your really quick answer. I will look at 
performSelectorOnMainThread, it sounds well.

Please, tell me: is it needed to create threads using GNUstep thread API, 
or may I use ordinary glibc pthreads? The whole application is written in 
plain C, requiring about 5 threads (2 camera threads, slower computation, 
disk file output, GUI) with different priorities, including a setting of 
SCHED_FIFO etc. I would really like to avoid GNUstep API for threads and 
use plain POSIX threads and to use GNUstep only for the GUI.


Many thanks,
Marek
