When I developed programs in Fortran 77, I did indeed have zero pauses, because all memory was allocated statically at the program start. With any form of dynamic memory, you have effort for managing that dynamic memory and thus pauses. The different technologies only result in those pauses happening at different times and other consequences. Modern GCs at least allow most of the necessary computation to happen in a parallel thread.
