Linux fork/exec latency is already pretty damn good compared to
solaris, I don't think its every been much slower, if at all.

If its slow on similar hardware, I would tend to think this isn't
what you are seeing.

I find shell scripts are slow sometimes - usually because linux uses
bash for /bin/sh where as solaris uses something more lightweight.

(Nice project for someone looking for something - de bloat bash)

Oh, as DaveM pointed out, fork/exit isn't uncommon, an he uses the
example of GNU configure scripts.

When I asked this, I did think about configure scripts and consider
them `not and everyday thing', likewise of interactive fork/exit in
shells.

But I have to concede, that I consider everyday things, and what
other people consider everyday things are not the same, and since
DaveM claims it make a noticeable different when building glibc, it
hard to argue its a good path not worth some optimization then.
