sadly not but i could reproduce it here again stuck in
but even running that 100 times shows no deadlock, seems it happens
only in a full fate run for me

also from looking at the code i see that finished could get set
while the other thread is waiting, i didnt check if that would deadlock
also iam not sure that fifo_cond should be reused
