From Jayadev Misra November 24, 2011 13:25:48 CST:

input sequence that leads to failure:

Restart Orchard. Then run KenKen using

include "http://www.cs.utexas.edu/users/misra/temporaryFiles.dir/KenKen.orc"

main()

I used the test sequence:

Board Size: 7
outline * : 483
===========================================
board size: 8

outline * : 1924 
outline + : 213 
outline * : 483
===========================================
board size: 9

inline + : 213 
inline * : 2404 
inline + : 233

This repeatably causes the failure with the currently deployed rev, r2888

One part of the cause:

orc.run.extensions.SupportForSynchronousExecution.runSynchronous does not 
return when Orc.stop() is invoked.

runSynchronous hang fixed in r2913

The other part of this bug is a limit somewhere in Jetty that is limiting Jetty 
to 8 outstanding requests.  Since the stopped executions were hanging, there 
still were outstanding requests for them.

The Jetty request limitation has existed in Orchard for years.  I'll consider 
this issue closed, but open issue 94 to increase that limit.

Fixes in r2914 deployed orc.csres Orchard WAR for testing.
