Subject: Re: Multithreading: I'm not complaining--I did something! (and it
 workson Windows)
From: alecgorge@gmail.com (Alec)

As an update, I fixed the crashing bug, the usleep bug (I don't know if 
it was really a bug, probably just a misinterpretation on my part), and 
the hanging bug. I fixed thread joining. I updated the samples and I am 
working on example05.php that will demo cURL!

Thanks to Tom R. who contacted me off the mailing list with a patch for 
the crash that would have taken me forever to track down!
