No, the PalmOS is not multitasking for user applications. The core OS
kernel on which it runs supports a fixed number of tasks, but only one is
reserved for the user interface layer in which apps run.

Accidental overwriting of database memory used by other applications is
prevented through a memory manager which write-protects all of memory other
than the application heap and stack, allowing writes only through checked OS
calls.
