Blackberry's don't work that way--no task-killers like Android. Using the built in memory-clear functions of the Berry and properly closing out of applications should be all you need. Also in terms of applications that hold onto memory or "leak" I would recommend adding applications to the device slowly and monitoring memory though the use of an application like FIXMOtools or others that have a memory monitoring feature to see which applications are the real, greedy, memory-snatchers.
There's no such thing as a task killer that watches over all applications. You have to manage things manually. I had to double-check all the time on my old 8320 so I didn't have to do a battery pull every 8 hours.
It's not necessary to watch over things anymore like a hawk with the 256 devices. The lowest I ever went on my 8900 was a hair under 70 MB and the device was fine.

Devices running OS 5.0 do not leak as much memory as they used to in OS 4.xxx. At least for me, memory "leak" is a non issue. upgrade to a leaked OS 5 on ur bold an you will see how memory is better managed with that os version.
