Yes, the two threads are running wgets under seperate processes with system.
 What operating system are you running? Vista?mipsel-linux with kernel v2.4 
 built from gcc v3.3.5

 Dear Micah:
  
 Thanks for your work of wget.
  
 There is a question about two wgets run simultaneously.
 In method resolve_bind_address, wget assumes that this is called once.
 However, this will cause two domain name with the same ip if two wgets
 run the same method concurrently.

Have you reproduced this, or is this in theory? If the latter, what has
led you to this conclusion? I don't see anything in the code that would
cause this behavior.

Also, please use the mailing list for discussions about Wget. I've added
it to the recipients list.

I reproduce this. But I can't make sure the really problem is in 
resolve_bind_address.
In the attached message, both api.yougotphogo.com and farm1.static.flickr.com 
get the same ip(74.124.203.218).
The two wget are called from two threads of a program.

 I reproduce this. But I can't make sure the really problem is in

Yeah, I get 68.142.213.135 for the flickr.com address, currently.

The thing is, though, those two threads should be running wgets under
separate processes (I'm not sure how they couldn't be, but if they
somehow weren't that would be using Wget other than how it was designed
to be used).

This problem sounds much more like an issue with the OS's API than an
issue with Wget, to me. But we'd still want to work around it if it were
feasible.

What operating system are you running? Vista?
