Failing without throwing from within job

[God-damnit-all]

I am wanting to abort a ThreadJob early if $LASTEXITCODE doesn't equal 0. Throwing accomplishes that, but I'm wanting the return value to only be the stderr output of the native application.

Here's what I would like if exit 1 hypothetically set the job's State property to "Failed":

$jobObject = Start-ThreadJob {
    curl --silent --show-error this_will_cause_an_error
    if ($LASTEXITCODE) {
        exit 1
    }
}
$null = Wait-Job $jobObject
$jobData = Receive-Job $jobObject 2>&1
if ($jobObject.State -eq 'Failed') {
    throw $jobData
}

And here is my current, ugly workaround:

$jobObject = Start-ThreadJob {
    $err = $(
        $out = curl --silent --show-error this_will_cause_an_error
    ) 2>&1
    if ($LASTEXITCODE) {
        throw $err
    } else {
        Write-Output $out
    }
}
$null = Wait-Job $jobObject
$jobData = Receive-Job $jobObject 2>&1
if ($jobObject.State -eq 'Failed') {
    throw $jobData
}

My problem with this is that the redirection wrapping you have to resort to is very kludgy, with $err being the outermost variable being set and the proper output set within a subexpression. I'm hoping for an alternative.

As mentioned before, exit 1 would be great, though I'm not sure how you'd feel about that producing a different State result from it being used in a BackgroundJob, since it doesn't work there either.
