And the only thing in set_security_attribute() which could take a lot of time is the call to LookupAccountName() which is only called if the /etc/passwd file doesn't contain the SID for the user *and* which can only take a lot of time if the machine is asking a DC. OTOH, set_security_attribute() cant have been called, otherwise it would have left footprints in the strace output. > > 97 7911229 [main] base 2872 fhandler_base::open: > >(C:\cygwin\opt\kde2\lib\cygkatecore.dll, 0x110000) > >*** big long pause *** > >11237820 19149049 [main] base 2872 fhandler_base::open: 0x19C = CreateFileA > >(C:\cygwin\opt\kde2\lib\cygkatecore.dll, 0x8 > >0000000, 0x7, 0x22F764, 0x3, 0x2000080, 0) > > cgf Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Developer mailto:[EMAIL PROTECTED] Red Hat, Inc. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
