----------------------------------------------------------------
Patch to fix the issue mentioned below.
I've left some TODOs in the code, which will likely be fixed in subsequent
jiras. Need information from someone more familiar with the code. (Some of the
comments read TODO: reviewer - those specifically need more info, ideally on RB)
Any operation which can block - e.g. processorContext.waitTillReady within the
hive codebase has the potential to lead to problems like this. To be fixed in
subsequent jiras. Some have been identified in the patch.
