me: well this is stupid, why did IBM sneak specifically Photoshop support under Win32s 1.30 and nothing else

ArcaOS: "we don't actually have a copy of the Win-OS2 source because it's encumbered by god knows how many companies"

thunks from hell

16-bit Windows calling a 32-bit driver pretending to be three VXDs in the VDM context which calls out to undocumented hooks in the OS/2 kernel to let Win32s allocations work

@luigithirty I read "the VDM context" as "a trenchcoat".
@pianosaurus not inaccurate since the driver masquerades as W32S, SHELL, and VTD.vxd to windows
