T3 Code theme step creates its mount file before the loop
A change merged into quattro creates the T3 Code mount file empty before a theme loop reads it, so a missing file does not end the install.
An update that themes T3 Code can stop while it reads a mount file the background job has not created yet. The loop hits a missing file and, with the shell set to exit on an error, ends the install. A change merged into quattro creates the file empty before the job starts. The loop reads it empty until the mount point is written.
The notes record that the new test run caught this on quattro's first run. In a virtual machine under load, the test failed 27 of 60 runs before the change, 22 of them on the missing file, and none of 60 on the missing file after.
