reassign 325553 libapache2-mod-php4
retitle 325553 PHP is not threadsafe.
kthxbye

Um.
PHP4 is, as the php group have said many times, is not known to be
threadsafe. Leaving aside how moronic this is, this means that a threaded
MPM like perchild cannot be safely used with the non threadsafe PHP4 module.
Your only reasonable solution is to use something like fastcgi or plain
suexec to run php4 scripts as cgis in the threaded MPM environment.
Also, severity inflation, which this is about as gratuitous a case as any
I've seen in a long time, does your cause no favours.
