Very interesting. Could you also try to find out the difference in terms of stat calls?

In general:

[alex@lancelot blm]$ strace -e stat64 python2.2 -S -c pass 2>&1 | wc -l 18 [alex@lancelot blm]$ strace -e stat64 python2.3 -S -c pass 2>&1 | wc -l 71 [alex@lancelot blm]$ strace -e fstat64 python2.2 -S -c pass 2>&1 | wc -l 8 [alex@lancelot blm]$ strace -e fstat64 python2.3 -S -c pass 2>&1 | wc -l 71 [alex@lancelot blm]$

Of the stat64 calls, the found-files only:

[alex@lancelot blm]$ strace -e stat64 python2.2 -S -c pass 2>&1 | grep -v ENOENT | wc -l 4 [alex@lancelot blm]$ strace -e stat64 python2.3 -S -c pass 2>&1 | grep -v ENOENT | wc -l 12
