Policeman facing a long cycle is undecided (9)

I believe the answer is:

dithering

I'm a little stuck... Click here to teach me more about this clue!

'cycle is undecided' is the definition.
I can't judge whether this defines the answer.

'policeman facing a long' is the wordplay.
'policeman' becomes 'di' (abbreviation for Detective Inspector).
'facing' means one lot of letters go next to another.
'a long' becomes 'thering' (I am not sure about this - if you are sure you should believe this answer much more).
'di'+'thering'='DITHERING'

Can you help me to learn more?

(Other definitions for dithering that I've seen before include "Flapping, hesitating" , "in a tizzy" , "Being indecisive" .)
