Is `record.set(value)` thread safe? #142

Closed coretl closed 6 months ago

coretl commented 6 months ago

@evalott100 needs to set a PandA record from another OS thread (file writing, hence OS thread rather than coroutine). Is record.set threadsafe, or does it need to be done from the same thread each time?

I would expect record.set to be thread safe ... on the whole. Writing to the same record from multiple threads can result in surprises, but I don't think there is any fundamental constraint here.

Think this ought to be a conversation rather than an issue.
