how do you all monitor that?

hey, i think this is a legitimate question. i was looking in

zinc_compile.py

earlier for a separate reason, and it subclasses

JvmCompile

, and at the bottom of

JvmCompile.do_compile(self)

(called by the

self.execute()

method), you can see

exec_graph = ExecutionGraph(jobs, self.get_options().print_exception_stacktrace)

. if you then look in

execution_graph.py

,

ExecutionGraph

is what i thought handled the parallelism directly, but actually it's

WorkerPool

-- at the top of

worker_pool.py

you'll see at the top of the file

from multiprocessing.pool import ThreadPool

. I would probably look there to see what mechanisms there are for managing and querying the status of individual threads (which is a generally useful sort of thing to think about, i think).
