SetModelScale + Collisions lead to infinite loops and server crash

[BlackOverride]

Steps to re-produce ->

create a prop physics model normally and scale it to some big size and let it collide multiple times fast cause instant infinite loop and crash -

local dome = ents.Create("prop_physics")
dome:SetModel("models/props_phx/construct/glass/glass_dome360.mdl")
dome:SetPos(self.Owner:GetPos())
dome:SetCollisionGroup(COLLISION_GROUP_NONE)
dome:SetMoveType(MOVETYPE_NONE)
dome:SetHealth(1000)
dome:SetModelScale(dome:GetModelScale() * 180) -- High values (x50+ on that model) cause infinite loop crash when collides more than once with other props
dome:Spawn()
dome:Activate()

Just like that, try to collide it multiple times per sec will cause overflow, infinite loop, and instant crash.

Same thing happens when using tools like -
https://github.com/Metastruct/advresize
or spawning from dupes

I also noticed that issue from long time ago which not sure why it was closed since it's not really fixed
#3547

I just want a reliable way to scale props with their collisions boxes for server side because I do need it to collide but there seems to be no way to do that?
