How about resizing a handle? I have a notifier that works under X which uses PtrAndHand to append the received data to an existing handle, which is monitored in a separate thread. Will that also work under 9?

From what I can gather from the docs, that you must use the OTMemAlloc and
OTMemFree calls for any memory stuff, as basically you are running at
interrupt time on 9.x. So the usually interrupt safe coding is required, and
to be quick in what you do. (X your are a separate thread from what I'm seen
from the debugger.)

While I cant specifically answer your question concerning notifiers. I
want to reiterate that OTMemAlloc can and will fail. OTMemAlloc is an
interrupt safe sub-allocator with a small amount of memory to work with.
You _must_ be prepared for OTMemAlloc to fail.

Just a friendly warning from experience. :-)
