on some 7.3 and 8.0 systems (actually all I tried) I'm seeing a strange
vi problem that's 100% reproduceable for me:

- open an xterm
- run vi
- close the xterm without exiting vi properly

Now vim immediately uses all of the available CPU. It can only be killed
using kill -9.

It seems that this happens since updating the kernel and glibc.
kernel-2.4.18-27.8.0
glibc-2.3.2-4.80

However, this also happens on some 7.3 systems where I only upgraded
glibc:
glibc-2.2.5-43
kernel-2.4.18-17.7.x

It does not happen on one 7.2 box where I'm still using the old glibc:
glibc-2.2.4-31

It also doesn't happen on a Red Hat 9 system (without glibc updates):
glibc-2.3.2-11.9
kernel-2.4.20-8

It still works fine after updating to glibc-2.3.2-27.9


I then attached to one vim process with strace. I got thousands of lines
like this:

--- SIGSEGV (Segmentation fault) ---


That's quite an issue on multi-user systems ...
