is there any authoritative documentation on when exactly the SolarMutex
should be locked when coming from the UI?
i know that it must be locked on UNO API method entry in the parts of
the code that are not otherwise threadsafe, but i have no idea how the
UI stuff / VCL works.
for example, somebody has put a DBG_TESTSOLARMUTEX() assertion in
ImplWindowFrameProc, which can easily be triggered by just creating a
new Writer document, entering a letter or whatever and hitting the
'Save' icon.
now which frame in that stack should lock the SolarMutex ?
