Nope.
But if you do, be sure to implement client (open/close) reference counting so the
library won't be released while it's still in-use, and remember that's actually up to
the caller to handle correctly not the library. And conversely, if you don't, be sure
to handle multiple calls to open/close appropriately. In any case, don't call any Palm
OS API in your library's sleep and wake routines which might perform interrupt-unsafe
actions.

Nope.
