Packet output mix up and server desync

[RotemNavon]

There is an edge case when using async and regular bofs together.
If an async bof is ran, and simultaneously a regular short bof like "uptime" runs, everything works great.
But if the regular bof is blocking for more than the sleeping time (for example sleep is 4 sec and bof takes 10 sec) then 2 things happen:

1. Output mixup both in console and in tasks view:

2. No output from the async bof is printed from the moment the mixed output batch arrives until the task finishes, possibly because of some desync that happens.
