To see for yourself, make clean then make all install in /usr/src/lib. Whilst in libc, I saw well over 130Mb of swap being used. It used to be at most about 30-40Mb. Also, running that peice of freshly committed TCL to find out what shared libs are being used, the wired-down memory jumped to over 20Mb. On a 24Mb machine with at most 70 processes running, this is no mean achievement. As you can imagine, it was paging like crazy. Johgn, is this related to the stuff from Alan Cox that came through recently, or is the VM collapsing code that was ifdef'd out? Stephen
