Subject: asyn interrupt and record

If I have a custom record...
And it has some procedure to respond to an ASYN interrupt.

As I understand it this asyn interrupt run in a different thread than
the dbaccess for the record?

This means in effect that if I have some array field and start editing
it in the interrupt function.
Then the db access/ca can get half-way modified values back?
Which would be bad?

Any method that the array can mutex/lock its fields while processing
them?

Or is it ok to edit?
