[coll] threading multiple operations

Hello guys !!!!!!!!

did some of you experienced any problems with threading some multiple operations on a [coll] ?
What i mean is (as example) :
i have a [coll] that contain numbered-symbols as indexes ( abc1 ,abc2 …. abc99 . uuu1 ,uuu2 … uuu99 . and so on ) .
Im doing operations like : swap , move , delete , dublicate by using one main [coll] and second for dumped data that has to be operated .
after desired tasks im replacing main [coll] content with the right one .
Everything is proved considering operations order and dumping tricks .
The thing is that i want to do the same operation on any numbered-symbol index in one time (i know its not asynchronous) . For all "abc" ,"uuu" etc . simply on and any other symbols that represent the same order .

Is there a chance that i will disturb operations while banging the same procedure for each dedicated symbol i want to affect (bang one after another) ?
note that every numbered-symbol index has its own engine to provide that operations . it contains the same set of [coll]s with the same name . Just banging one engine after another (without waiting for the first one to be finished) .

Ive checked it on only 3 sets of different index symbol ,and i havent noticed any flow problems , but im wondering if i can expect some aliens with more of the data to maintain . Would be great to know such thing before i start to implement the whole system which is quite complex at this level already :/

If someone know something about threading multiple operations on [coll] please please share your warnings or tips if you think are necessary .

greetings
