Powershell Jobs not finishing when using Move-VM

This is a script block from a larger script I am using to feed it parameters. The background job never finishes if I leave off the -runasync flag. The task completes fine in VC, but I don't see any of the write-hosts in the job output after the Move-Vm line.  I have tried this in both powershell v2 and v3 with powercli 5.0 and 5.1 . Any ideas?

$vCenter = "VCenterName"

$DestinationDatastore = "DestinationDatastoreName"

$VMName = "VMName"

$Account = "Username"

$VIPass = "Password"

# Define Job Parameters

$jobcmd =

{

     $in = $input.'<>4__this'.read();

     Add-PSSnapin VMware.VimAutomation.Core

     Connect-VIServer $in[1] -User $in[2] -Password $in[3]

     Write-Host "Getting VM Object"

     $JobVMObject = get-vm -Name $in[4]

     Write-Host "Getting Datastore Object"

     $JobDatastoreObject = Get-Datastore -name $in[5]

     Write-Host "Moving VM"

     Move-VM -VM $JobVMObject -Datastore $JobDatastoreObject -Verbose:$true

     Write-Host "Im Done Moving"

     Write-Host "Disconnecting from VCenter"

     Disconnect-VIServer * -Confirm:$false -Force:$true

     Write-Host "Disconnected"

} 

$jobSpec = @()

$jobSpec += $jobcmd

$jobSpec += $vCenter

$jobSpec += $acount

$jobSpec += $vipass

$jobSpec += $VMName

$jobSpec += $DestinationDatastore

Start-Job -InputObject $jobSpec -ScriptBlock $jobSpec[0]

Wait until the task in VC completes, then run this command, and you should see that the job doesnt progress past the move-vm command.
