One change from 0.53 is that FreeTDS no longer identifies itself as an ODBC
driver (unless the ODBC driver is used).  That affects default column
nullability (and other things).  I don't see how that could affect anything
here, but it's worth keeping in mind.  

If we could see a TDSDUMP log, that would help.  It's possible, as Frediano
says, that DBD::Sybase is opening a second connection.  That would explain
the nonexistence of the temp table.  

It's also possible FreeTDS is falsely reporting busy-ness, inducing
DBD::Sybase to create a new connection when it doesn't (as far as the
server's concerned) really need to.  If that's the case, you've got our full
attention, because we'd want that fixed before the release.
