Why don't you want to utilize the Imp. Shadow Bolt proc? Reserved for Shadow Priests and their Mind Blast or what?
It's not consumed by DoT ticks, so if you're an Affliction Warlock and there isn't a Shadow Priest (and the other 'Locks are Fire Destro) you can just let it sit up there for the whole duration of the effect and bump your Corruption/Siphon/CoA damage. You want it to remain for as long as possible, so if you can... let it sit up there a little longer, then start throwing more Bolts to refresh it. It's not a bad time to throw Immolates.
The situation changes somewhat based upon the number of Shadow-damage dealers in the raid, of course. If there's a lot of Shadow Priests it's probably going to be consumed almost instantly and you may be better off to just keep spamming it - if you don't get the benefit from it, someone else will, and reapplying it gives a large damage boost. On the other hand, you can work out a system with the Shadow Priests/others Locks in your raid to conserve the proc - such as a shared chat channel warning when it's up, and having the Priests refrain from using SW:D and only casting Flay/Blast to let it stay up longer. There's all sorts of neat things to do with it. *shrug*
It's a lot like Stormstrike, really. If you have any Elemental Shaman in the raid, an Enhancement Shaman casting Earth Shock is a huge waste if it's consuming Stormstrike procs. It'll lower your DPS on the meters, but lead to a much larger gain overall if you let the Elemental Shaman take the procs. (Also less likely for you to die, which is always a plus.)
