------------------------------------
Hi Jonathan,
There are two things:
# Single Pig job in local mode (LocalJobRunner).
# Multiple Pig jobs in the same VM as you mentioned.
The direct motivation for this ticket is (1), but I am doing some experiments
with (2) where I execute multiple jobs in a single VM.
Thanks!

> There was a race condition reported when running Pig in local mode on the
> user mailing list. This motivated me to fix potential multithreading bugs
> that can be identified by FindBugs.
> FindBugs identifies the following potential bugs:
> # Mutable static field
> # Inconsistent synchronization
> # Incorrect lazy initialization of static field
> # Incorrect lazy initialization and update of static field
> # Unsynchronized get method, synchronized set method
> There are in total 1153 warnings that FindBugs complains, but they're outside
> of the scope of this jira.
