Public bug reported:

I'm uninstalling Steam (with a two or three applications installed under steam.
I expect an uninstallation process to take a couple of minutes max.
What I'm seeing is somewhere between odd and suspicious.
It's taking  45 minutes to uninstall Steam, and this is on a machine with an 
Intel Core i9 14900KF (32 cores), 64GB RAM, and a very fast SSD.
BTOP is showing gzip slammed for processing power and snapd taking up a bit.  
Nearly all cores are idle and it would appear from my untrained eye that gzip 
is limited to 2 cores which seems to be the root cause of this problem.  I see 
two cores being used significantly: both between 35% and 75% changing with 
every refresh of btop.  

I find it hard to imagine this is not a bug given the absurd time it
takes to remove an application.

Ubuntu 25.04 fully updated
Steam latest/stable 1.0.0.83
Expectation: Quick removal of software package from system.
What happened: An interminable wait as gzip is doing gawd knows what.  It 
shouldn't be used in a software removal process.  This is the suspicious part.
