This has nothing to do with 'fork' per se, but rather all system calls.
System calls on most OSes are handled via interrupts, which can get stacked
up under heavy load.  Since the 'fork' call happens so much in *nix, it has
been heavily optimized over the decades and it's _very_ fast, but only when
the kernel gets around to executing it.
