Not exactly.  For example, I see this under alib:

alib    
  0.4.0
     alib-0.4.0.gem
  0.4.0
     alib-0.4.0.tgz 

Instead of just:

alib
  0.4.0
     alib-0.4.0.gem
     alib-0.4.0.tgz
  
I didn't even realize that GForge allowed identical release names for
the same package.  Maybe this has nothing to do with the problem,
however.  I'm just guessing.

It would require C I'm afraid.  The win32-open3 package is one of those
that can't properly be converted to pure Ruby.  Perhaps a simple facade
is in order.

I haven't looked at the source yet, but I suppose I would start with
Lock() and LockEx():
