Re: [ANNOUNCE]: LuaThreads 1.0-work

["Peter Loveday" <peter@...>]

Excellent, thanks for that!

I've just got it compiled and running; I had to modify Lua.h a little, as
there seems to be some problem with the l_s() macro not being defined for
lthreads.c, which causes errors when using lua_ref() macro.  I presume
it needs to define LUA_PRIVATE, though that would prevent any libraries
from creating static strings from C code to pass to Lua unless they too
were defined with LUA_PRIVATE.

One small problem I've come across, when breaking the example child/parent
flood, it takes two breaks (ctrl-c)... one kills one thread, but the other
thread continues.  Probably best if the break killed the process, having
a thread quit by the user would be quite difficult to deal with gracefully.

Thanks again for the changes.

Love, Light and Peace,
