OK, current behaviour is that if I launch a thread after thread there is no
problem at all as long as I go for Sleep(10) ms after calling it, so
majority of threads get executed then sequentially. If I limit this time to
1ms, although I allow maximum of 8 custom threads of mine to run, it
occasionally crashes for SetNumberOfThreads(1) set in resample filter. If I
remove this limitation, then it crashes very quickly. This still gives me a
hunch that the actual Update doesn't wait for completion of all threads of
resample filter (or some other wacky behaviour takes place). Otherwise,
there may be still a silly bug somewhere in my own code, although I cannot
see no other reason for this no more.
