LogTail was read by the progress loop while the output pumps appended to
it. Blender rewrites its status line many times a second, so the first
progress report of every job threw; aerender hit the same race only rarely.
LogTail now locks internally.
The exception also escaped BlenderRunner without ending the process, leaving
blender.exe rendering unsupervised on the node on every failed attempt. Any
unexpected exception in the monitor loop now kills the process tree.
Bump worker to 1.6.2.
