Update final docs with new heartbeat default.
schemachange app: fix hang in loadtable when connections are lost and duration time expires
WIP jenkins script to clone jobs and change some properties
schemachange app: setdaemon on worker threads so they die if the main thread
exits or throws an exception. Retry the unsuccessful catalog update case.
Resize java plan cache to use less heap memory. Here is hoping this works
Back-patched 3 small diffs from "future" hsqldb 2.2.8, MIGHT solve the intermittent HashIndex.java ArrayIndexOutOfBoundsException.
schemachange app: Limit outstanding txn in table load.
    Replace progress timeout assert with an error message.
    Add progress reports to table load.
    Add debugging msgs to table load.
    nb. Table load is quite slow. The runapp-recover test does cluster recovery during this time.
    This is mostly counterproductive. Should investigate way to coordinate the app and apprunner
    to concentrate recovery testing on the schemachange operations.
Merge branch 'release-3.2'
