Yeah, it happens frequently that the Java side dies without calling
`close()`, for example when the TaskManager encounters an unrecoverable error
and terminates.
+1 for having a safety net, timeout sounds good. It can be a rather high
timeout, though (order of several minutes)
Ideally, the python process would also be a child process of the JVM
process, to it is killes anyways by the kernel when the JVM process exists, as
another safety net.
