///**
// * Tests the following sequence of events:
// * 1) Workspace operation starts in the UI thread. Workspace lock is taken, and a modal context thread is forked (call this modal context MC1).
// * 2) Operation transfers the workspace lock to MC1 using IJobManager.transferRule
// * 3) Operation runs in MC1, scheduling an asyncExec.
// * 4) MC1 passes the scheduling rule back to UI thread, and exits
// * 5) After passing the rule back to the UI thread, but before MC1 dies, the asyncExec is run.
// * 6) The asyncExec forks another model context (MC2), and blocks the UI thread in another event loop.
// * 7) MC2 tries to acquire the workspace lock and deadlocks, because at this point it has been transferred to the UI thread
// *
// * NOTE: This bug has not yet been fixed. This test illustrates the problem, but must
// * not be added to the parent test suite until the problem has been fixed.
