How or why did I choose a certain keyword? Here I will try to log all words which were not 'evident'.

bounce

reconsider: To long, and doesn't give the 'move' idea
plan_b: Funny, and gets the right feel, but funny is not good
renege, desert: To negative, also misses the idea of going somewhere specific
defect: To negative
switch: Overload of 'C' switch: dangerous
correct, fail: Doing a 'bounce' is not wrong per se, which there words seem to imply
migrate: Tapes, storage, but has no process connotations
divert: Active/passive problem, it reads like diverting something, but not the program flow
bounce: Bouncing email, the best word till now
