Ok, that is almost exactly 10 seconds longer than it should take.

And I can almost guarantee that it's something like a problem looking up 
your hostname or perhaps user identity - I would guess you have some name 
service problem.

Do an

	strace -tT git commit --message "initial commit"

on that git commit to make sure, but I would almost bet that it's when git 
does tget "getpwuid()" thing to get your name from the gecos fields, and 
you have some setup problem with nscd o similar.

It might just go away if you set up your user name and email manually, ie 
try doing

	git config --global user.name "James Utter"
	git config --global user.email james.utter@xxxxxxxxx

and see if that makes the delay go away. It probably tries to look up your 
login info from some non-existent NIS setup, and then times out after ten 
seconds and picks the data from your /etc/passwd file instead.

(There can be other things that do similar things - misconfigured name 
servers etc can cause delay etc. So maybe I'm wrogn on blaming nscd, but 
it would be my first guess).
