Why does the Install-SPSolution / Uninstall-SPSolution take exactly 8 hours to complete?

Question

I asked this question
here before and didn't get a usable answer and I see other people are getting the same issue. I did some more testing, added a timer/t to my scripts and discovered that the Install-SPSolution / Uninstall-SPSolution always takes exactly
8 hours to the minute to complete, no matter when I start it. I verified this over several refreshes of my webpart and it is always exactly 8 hours. This applies to both Central Admin and farm solutions. I hope that the duration of 8 hours
to the minute does contain a clue to solve this issue.
This is the PS1 script I use to install the CA component:
param([string]$cadmin2010 = "", [string]$cadmin2013 = "")
Write-Output "Installing MySolution.CentralAdmin.wsp webpart"
Add-PsSnapin Microsoft.SharePoint.PowerShell
Write-Output "Loaded SharePoint environment"
$cadmin = $cadmin2010
if ($cadmin2013) {$cadmin = $cadmin2013}
Write-Output $("Installing webpart on " + $cadmin)
$sln = Add-SPSolution MySolution.CentralAdmin.wsp
Write-Output "Added solution"
Install-SPSolution -Identity MySolution.CentralAdmin.wsp -GACDeployment -Force
Write-Output "Installing solution"
while($sln.JobExists)
start-sleep -s 5
Write-Output "Solution installed"
Enable-SPFeature -Identity b2ff3a66-0f9d-4b4a-9b79-842aeca34d42 -url $cadmin -Force
Write-Output "Feature enabled"
It takes 8 hours before the "Solution Installed" message is printed. Once it completes, everything works fine, but with the uninstall of an old version and the install of a new version, 16 hours is a long wait. This is the output of my script:

Please use this code for waiting to deployment finish (it shouldnt take so long):
$solutionFileName = "something.wsp"
$timeout = 1000
$jobName = "*solution-deployment*$solutionFileName*"
$job = Get-SPTimerJob | ?{ $_.Name -like $jobName }
if ($job -eq $null)
Throw "Timer job for '$solutionFileName' not found"
$jobFullName = $job.Name
Write-host "Waiting to finish job '$jobFullName'..."
do
if($timeout -le 0)
Write-host "Failed: timeout"
Throw "Job '$jobFullName' not finished after "+ ($timeout * 2) + " seconds"
Start-Sleep -Seconds 2
Write-host . -NoNewLine
$timeout -= 1
} while ((Get-SPTimerJob $jobFullName) -ne $null)
