Default distribution buffer size and max process limit are unintentionally excessive

[michaelklishin]

As of 118b448 they are 10 times greater than the values we discussed. We are yet to confirm from the contributor of the change but this is unlikely to be intentional.

The distribution buffer default, for example, can explain some of the "absurd distribution buffer size" runtime terminations that @dcorbacho and I have seen in the last few months.

Per discussion with @lukebakken. Originally reported by Chris Friesen.

Curiously in practice the max number of atoms wasn't bumped (tested with 3.7.6 and 3.7.7 nodes) but the distribution buffer was.

Ouch! That was my ego, definitely not a cool mistake.

Thank you Chris for spotting this & @michaelklishin for turning it around so quickly.

@gerhard no worries. I introduced a typo while fixing this 😅 but luckily Chris spotted that, too 🥇
