Some sleep did the trick. I had this #ifdef in my earliest experiments but forgot about it this time. This code works:
void crypt_all(int count)
{
enqueue(Transfer);
enqueue(RarInitKernel);
for (i=0; i<HASH_LOOPS; i++)
{
enqueue(RarLoopKernel);
+ #if !OS_TIMER
+ sig_timer_emu_tick();
+ #endif
+ clFinish();
+ if (event_pending)
+ process_event();
}
enqueue(RarFinalKernel);
I will apply this to various formats and check for regressions.
