Yes, but I noticed that when there are no events, OnIdle is fired even 
so (at 5 seconds cycle). I thought it was enough to catch signal, but 
maybe it's too long and signals may have short live. C example uses glib 
main loop to check signals. I see that free pascal have some glib 
librarys. Can I somehow use it (I do not know what it is)? I need this 
solution only for linux
