Subject: RE: Ruby threading and GUI toolkits

Well, I actually apologize.

What I need to do is be able to start <n> number of Threads before the UI
mainloop and then start that mainloop in its own thread.  I have been trying
this on Win32 on the mswin32/1.7.2 (not cygwin) build.  I just tried a slew
of stuff under cygwin and it works great (tk, fox...have not tried gtk).

I tried VRuby.  It ONLY lets you set an idle proc but starves other threads.
This was the first UI toolkit I used and gave me a false first impression on
other toolkits.

I tried Fox. It works great under cygwin..but blows up under the mswin32
build when other threads are present.  I contacted Lyle about it...and he is
going to look into it.

I have not run tk under mswin32...but I'll give it a try.

Just needed more exploration before asking ;-)
