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.
