Patches are free-floating code snippets, so they do not have global variable
data. They inherit the stack of the currently running procedure, so should
not use excessive amounts of stack space. The dynamic heap may be filled or
empty, depending on whether or not the running program is using it
extensively (only use this for temporary storage, since dynamic heap space
is extremely precious). Patches may access databases and resource files and
features in order to retrieve configuration data stored for them by the
control panel routines.
----
It may be possible for a hack to allocate a fresh stack, change SP to point
to it, then fix things upon leaving, but it is left as an exercise for the
reader.
