Sorry, just to clarify, if I do *not* set connect=False when
initializing dev.PV, then the enum_strs attribute is set properly.  In
other words, it appears to only be set if the pv is able to connect on
initialization.  If connect=False, the created pv does not get enum_strs
set, nor does it ever even after a connection has been made.
