Take into account that there are a large number of DSOs and that they are sometimes used. Most of the time only a small fraction of any DSO is used in a program. Using madvise to get the DSO loaded will likely waste a lot of resources. I've been thinking about adding a special flag to system libraries so that at least they can be handled this way. But it is a bad idea to do this in general. If you want to convince me try using a large number of programs using lots of DSOs in an OS environment with limited memory. -- What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |WAITING http://sourceware.org/bugzilla/show_bug.cgi?id=11431 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
