A decreasing number is one whose digits (left to right) decrease in value

This is plain wrong: it's named decreasing when it's actually non-increasing.

Note that in the other kata, Increasing Numbers with N Digits, the description makes it very clear it's non-decreasing.

Why is the user solution called get_pid? Hostname and PID are two totally different concepts.

There are 64 decreasing numbers below 100:

[0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 
 10, 11, 20, 21, 22, 30, 31, 32, 33, 40, 
 41, 42, 43, 44, 50, 51, 52, 53, 54, 55, 
 60, 61, 62, 63, 64, 65, 66, 70, 71, 72, 
 73, 74, 75, 76, 77, 80, 81, 82, 83, 84, 
 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 
 96, 97, 98, 99]

But the expected answer for digits = 2 is 65.

It would be helpful to provide an actual definition of a 'bouncy number' rather than mere examples. More than one possible definition matches the given examples.
