Yes. And as far as I know both of the OS2*.INI files are included in
this "data" and are kept in memory and occasionally written to disk.

This makes no sense. If a program uses WPS calls to modify OS2.INI then
the WPS gets these calls and updates the data. If a program uses a WPS
call then "making the change" and "notifying WPS of the change" are both
done with a single call, the same call. Yes?

It shouldn't make any difference if the WPS first has to shove the
update into a memory buffer and from there eventually caches it to
OS2.!!! which gets written to OS2.INI on shutdown. And if a program
makes a call to the WPS with an update while the WPS is moving the
memory buffer to the disk cache then the WPS shouldn't "lose" the
update, it should just put this new update into the memory cache for the
next buffer flush to disk.

Are you saying that somewhere along this linear data flow the WPS is
internally broken and "loses" updates?
