If prelink chews on a binary that's currently running, its /proc/self/exe
essentially goes away. Which can be undesirable, for a persistent daemon
process.
It took me a while to figure out why my daemon kept breaking all the time,
when it couldn't stat its /proc/self/exe any more.
I suppose I could blacklist it, in prelink.conf. But that seems wrong.
prelink should either avoid touching binaries that are currently loaded, or
there should be a way prelink can coordinate its activity with binaries.
