Well, sort of . They should be able to run concurrently unless the 
python client maintains transaction locks
over the whole session and same patient data is being opened, which it 
doesn't  AFAIK , and neither does the web client.
The web client inserts data only on submit : this can be transactional 
over all the items entered, but at the moment,
it can fail one clin_item insert while allowing the others ( after 
successfully inserting a new episode +/- health issue )
if no clin_items are inserted , then the original committed transaction 
of episode insert is reversed by a delete/commit.
(although I think any new health issue stays in the record) .
The python client creates empty rows on object creation, and I think 
these objects update the database when
triggered by  a save command on a widget. On the other hand, some tables 
such as clin_medication are guarded
by a lot of constraints, and objects in this case might be easier to 
just do table insert .

The web client can put data into the schema , with it's current 
constrains intact, and extract it out again,
but the python client does it only for some records updated by the web 
client. It's either a bug , or  a python client  (not backend) enforced
validation error .  That's on my TODO list .
