(which proved that getlogin returns the > wrong value sometimes..) getlogin depends on internal variable _logname_valid which is set after first sucessful getlogin call, then getlogin simple return its static data and even not issue syscall!!! How perl calls C-functions, it is the question... Maybe it call each C-function in the fork? I.e. _longname_valid always 0 for getlogin? Then it is perl bug, it seems that it change uids on the fly, then call getlogin for each of them. -- Andrey A.
