 Fairly quickly in this case depends on the definition, which needs to be 
probably rather loose in the case of not using inotify and having a somewhat 
slower machine. Do you want to bet how many bugreports will we[*] get from 
users who run install-fooapp (which installs fooapp and as the very last step 
installs the menu entries) and immediately after it's done will try to find 
fooapp in the K-Menu and will have trouble with it, because it'll need some 
time to show up?

[*] "we" meaning both KDE and xdg-utils getting their share, probably

 And while it's not that kbuildsycoca definitely has to be run, it'd just be 
very nice if it would. And if it can be done, and I hope my answers below 
solve your issues, why not avoid the possibility of the problem for a vast 
majority of the cases?

 Hmm, I knew it wouldn't be so simple, it's rather stupid of su to completely 
discard the value of $HOME :(. But it could be simply tested if the value of 
$HOME is found in /etc/passwd and not do anything otherwise, just having it 
the same way it's now.

 They are already called from sudo, so it should be sudo from root to another 
user. I don't think su or sudo ever need a password for the from-root case. I 
could make an explicit check for $UID being 0 in the sudo case though.
