[gentoo-user] prelink on AMD64 with no "--conserve-memory"

[Nikos Chantziaras]

(I originally posted this on gmane.linux.gentoo.amd64, but even though 
GMane authorized me to post there, my posts don't get through.  So I'm 
reposting it here.)

Usually, when prelinking a system, it's recommended to use prelink's 
"-m" (or "--conserve-memory") option:

   When assigning addresses to libraries, allow overlap of
   address space slots provided that the two libraries are
   not present together in any of the binaries or libraries.
   This results in a smaller virtual address space range used
   for libraries.  On the other hand, if prelink sees a
   binary during incremental prelinking which puts together
   two libraries which were not present together in any other
   binary and were given the same virtual address space slots,
   then the binary cannot be prelinked.  Without this  option,
   each library is assigned a unique virtual address space
   slot.

But on AMD64, virtual address space is virtually unlimited (or at least 
"very huge").  Are there any drawbacks in not using "-m" on AMD64?
