This should be exactly what lua_yieldk does. (at least in my software
it works like this without problem ... just condition is, that you
invoke lua_yieldk ONLY in a valid thread / resumed thread (NOT
directly from the Lua state - so you can use lua_yieldk nicely, if a
Lua user in the Lua code wants to specify a "Lua coded" command
string. But you can NOT use lua_yieldk, if you get such a "Lua coded"
command string from "somewhere else").

Sorry, this is a bit away from my application. Could you perhaps try a
more simple example, which really has VERY few C code lines to
demonstrate your problem (e. g. use a very simple sleep functionality
or somehting like this).
