[PATCH] fix file and descriptor handling in perfmon
Races galore... General rule: as soon as it's in descriptor table, it's over; another thread might have started IO on it/dup2() it elsewhere/dup2() something *over* it/etc. fd_install() is the very last step one should take - it's a point of no return. Besides, the damn thing leaked on failure exits... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
