This has been a trouble spot with Shadowrun from the beginning, but it doesn't have to be done 'on the side'. It is tricky to manage, but with practice most GM's should be able to integrate the hacking with the actions of the rest of the group. It is better for everyone if the plot-turning matrix runs are part of a larger action, with the decker having to jack in under fire, or under the noses of Corp suits.
The GM and the Decker just speak a little different language as they weave the matrix narrative into the larger story.
For those side runs that don't really add up to much, just take the Decker player aside and tell them from now on, these little runs are going to be streamlined for the sake of practical game-play, but still take a couple of moments to run the matrix scene, or your deckers will might get bored, which is really not a solution to the original problem.
This,I always streamline matrix runs when I run shadowrun for the sake of speed, though I do like to keep some detail involved to keep hacker characters busy, on top of that it is fairly simple for hackers to branch out into other fields so that while their focus might be hacking they can take part in the rest of the action too. Talk about it with any players you think want to play hackers beforehand and see if they'll help you strike this balance.
