TxnDebuggable
This trait implements methods that can be used to examine the content of
transactional data structures in a debugger with minimal modification to
the behavior of the program. Normal transactional reads would add to an
atomic block's read set, which could reduce the number of valid program
execution orders. dbgStr and dbgValue perform transactional reads,
but then erase them from the enclosing transaction (if any).

You can use these methods from an IDE debugger manually, by watching
x.dbgStr or x.dbgValue rather than x.
If you use Eclipse, you can make this method the default view by going to
''Window->Preferences->Java[+]->Debug[+]->Detail Formatters'' and
entering the code snippet dbgStr() (or dbgValue()) for instances of
scala.concurrent.stm.TxnDebuggable.
If you use IntelliJ IDEA, go to
''File->Settings...->Debugger->Data Type Renderers'' and create a new
renderer for scala.concurrent.stm.TxnDebuggable that uses
dbgStr() for rendering and dbgValue() for node expansion.

Abstract methods
Returns a string representation of the transactional value in this
instance for debugging convenience. The Ref reads (and writes)
performed while constructing the result will be discarded before
returning. This method works fine outside a transaction.

If this method is called from within a transaction that is already
doomed (status Txn.Rolledback), a string describing the reason
for the outer transaction's rollback will be returned.
