Hi Eliot,

The snippet below, evaluated from a workspace, triggered the issue in less than a minute for me, three times in a row. Both processes will halt if #sloppyWaitForDataIfClosed: doesn't return within a second. If you send #dataAvailable to the socket, you'll find that it has data ready to be read, but its readSemaphore has no signal.

does it happen if you have strace -o output.txt -f on the VM as well? kind regards holger
