   One more thing about getdents() in linuxolator 2.4 with bsd<=7 (the
   working one, with old glibc etc.).
   It consumes substantial amount of cpu ticks reading
   large directories. This problem was there since 4.x. You can
   replicate it using Valve's software "steam" content distribution
   client. ./steam consumes 100% of cpu when updating/fetching files.
   Until now, we thought that this is steam software problem, but it
   turned out, that the problem is non existent on Linux (steam
   consumes ~0-1% cpu).
