    Please add timeout parameter, e.g.
    -  @Test
    +  @Test (timeout=300000)

bq.  Summary
bq.  -------
bq.  
bq.  https://issues.apache.org/jira/browse/HBASE-4014 Coprocessors: Flag the presence of coprocessors
in logged exceptions
bq.  
bq.  The general gist here is to wrap each of {Master,RegionServer}CoprocessorHost's coprocessor
call inside a 
bq.  
bq.  "try { ... } catch (Throwable e) { handleCoprocessorThrowable(e) }"
bq.  
bq.  block. 
bq.  
bq.  handleCoprocessorThrowable() is responsible for either passing 'e' along to the client
(if 'e' is an IOException) or, otherwise, aborting the service (Regionserver or Master).
bq.  
bq.  The abort message contains a list of the loaded coprocessors for crash analysis.
bq.  
bq.  
bq.  This addresses bug HBASE-4014.

> For some initial triage of bug reports for core versus for deployments with loaded coprocessors,
we need something like the Linux kernel's taint flag, and list of linked in modules that show
up in the output of every OOPS, to appear above or below exceptions that appear in the logs.
