I'm trying not to :) The mistake I made was not including an esd.conf
file to stop libesound from doing it by default :)

No, there is no bug in pulse here, I just had a bug in my packaging of
the pulseaudio-esound-compat package where I did not provide an
/etc/esd.conf file.

When this file does not exist, the *libesound* autospawning was turned
on by default which resulted in pulse being auto spawned via
/usr/bin/esd -> esdcompat

Like I say it may not be an issue on fedora's libesound if it's been
tweaked accordingly.

Fair enough. Certainly the sounds are cached at login as I think I
reported back elsewhere so that's good :)
