           Summary: network app (SBClient) uses all CPU (2/3 sys, 1/3 user)
                    unaccounted
           Product: Wine
           Version: 20050419
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-net
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: leon-wine-bugzilla at cyberknights.com.au


While SBClient is doing network access, the CPU pegs and the app (the whole 
machine) runs very slowly, returning maybe one keystroke every 4-5 seconds for 
a LAN (100baseT) Telnet connection. None of the CPU time is accounted to any 
processes, it just sends the load average through the ceiling. Anything not 
involving network access (i.e. sitting at a prompt or waiting at a menu before 
starting the network connection) operates normally. 
 
Swapping MSVCRT to builtin doesn't seem to help. Downloading and installing a 
different native MSVCRT.DLL doesn't either. 
 
If you want debugging info or whatever, please ask. The only normal output is 
this line: 
 
$ wine sbclient.exe 
fixme:ole:CoCreateInstance no classfactory created for CLSID 
{ce9a1380-cc8d-11d2-9961-00a0c9b7589d}, hres is 0x80040154
