I agree this is VERY bad idea but the fact is that there is a code which does such nasty things. I truly hope all this will/was fixed in 2.5 but frankly I wouldn't be so sure :) Unfortunately, for production 2.5 is unusable and will be for some time. A lot of people (I think majority) still use 2.4. And 2.4 (as of 2.4.22-pre6) is still broken in this respect... Eugene ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
