Hello,

Thanks for the fix.

I have made some tests with the CVS version and I don't have anymore
not closed Handle, but I still have a memory leaks.

I have made 2 testcases :

$ gcc server.c -o server
$ gcc server.c -Dnoleak -o servernoleak
$ gcc client.c -o client

I execute sever.exe and client.exe

after 1 minute I have 2992Ko memory used by server.exe (see
http://www.netsolux.ch/cyg/5.gif)
after about 10 minutes I have 5156Ko memory used by server.exe  (see
http://www.netsolux.ch/cyg/6.gif)

If I execute severnoleak.exe and client.exe I dont have memory leak.

The memory leak seem to be in the poll (select) function.

Regards,

Thomas
