Oliver Soong reported having difficulties with memory leaks.  There are two
specific bugs about this, which I have set to block this testing bug.  In
addition, testing may reveal additional leaks, which should be fixed before 2.1
is released.  Here's Oliver's synopsis of the issues:

I think this is limited to the wrp suite, but Kepler’s performance degrades
significantly over time.  Provenance recording can become prohibitively slow,
and there is no native in-Kepler fix.  There is a large memory leak somewhere,
and many components are quite memory-intensive regardless.  Given the intention
to record executions and the large number of analyses scientists perform, I
suspect any dedicated user of Kepler will quickly encounter data management
problems.  In my case, I stopped using local repositories and began closing
Kepler after running any large workflows.
