37. This length is fixed.
I've looked marshal_str's code and my understanding is that it will pad the
string with '$' to fill the necessary 40, right? so what gets copied to buf
is actually something like "cdc19cac-527e-4e4b-b8f9-ef453db9e0d3$$$".
Also, I'm not sure why the fields should use LogAccess::strlen instead of
::strlen, but as all other string fields do so, I thought it was the right
thing to do.
