I can verify that a lot of weird problems (compiles failing with seg 
faults, `java -version` not running, other java programs not running and 
in most cases the program in question would succeed if I ran it through 
strace first) I was seeing in kernels after 2.5.18 (ie. 2.5.20-dj1, 
2.5.20-dj4, 2.5.23-dj1 and 2.5.24-dj1) go away if I reverse the patch 
included in the original email for this thread.  Glad to find out what 
had been causing that mess!  Thanks.
