Could it be that CreateProcessA is used wrong somehow?  I don't know the 
win32 api, but does anyone know if using it wrong (security settings or 
sth) could block new process from accessing the network?  Where would I 
start looking if I want to fix this?  The msdn docs didn't help much. 
Couldn't even find mention of this function, only CreateProcess, without 
the trailing 'A'.  But it seems to be the same function.

Here's what the call looks like:
CreateProcessA(null,std.string.toStringz(command),null,null,true,DETACHED_PROCESS,env,null,&startup,info)
