Error streams duplicated in every job

Bug

What is the current behavior?

Start-RsJob { $ErrorActionPreference = "Stop"; Write-Error "Break me!" }
Start-RsJob { Write-Host "Hi" }
Receive-RSJob -Id 2

Results in

Exception calling "EndInvoke" with "1" argument(s): "The running command stopped because the preference variable 
"ErrorActionPreference" or common parameter is set to Stop: Break me!"

Basically one failed job pollutes the streams of all the others.

Which versions of Powershell and which OS are affected by this issue? Did this work in previous versions of our scripts?

In PoshRSJob.psm1 there's a "Routine to handle completed runspaces" and that's what seems to extract the error and add it to each job.

But I don't understand why it's dragging them out of other jobs and then appending them to later jobs.

It's because you check $CaughtErrors and never reset it. Modifying it to this fixes the problem:

$PoshRS_jobCleanup.PowerShell = [PowerShell]::Create().AddScript( {
        #Routine to handle completed runspaces
        #$PoshRS_jobCleanup.Host.UI.WriteVerboseLine("Begin Do Loop")
        Do {
            [System.Threading.Monitor]::Enter($PoshRS_Jobs.syncroot)
            try {
                Foreach ($job in $PoshRS_Jobs) {
                    $CaughtErrors = $false

I fixed a similar error for $Data in #122, but did not look at the $errors :)

I'm not able to reproduce this anymore on the current build.
