i think this is not what is happening really..

i noticed a slowdown when i added a huge bunch of externals with
different paths to them.
so now i removed all and set the nessary once in one locations but with
subdirectories (by name, as appears in the cvs).
this seems to be fine ..

i think that ldconfig caches frequently used stuff in /etc/ld.conf.cache
but still keeps only file descriptors in the memory ..
