Humanities - taking a year off between PhD completion and academic job
I'm in the humanistic social sciences. If you were my doctoral student, I would suggest that you delay depositing your dissertation. This is even though there is considerable pressure from my institution to hurry students out (part of the NRC university rankings is time-to-completion so the provost puts pressure on faculty in this regard). 

If you can afford the continuous registration fee and the university does not put onerous rules to make life difficult, then there are many more pros to cons.

Pros:


You can work on your publications as if you are a post-doc.
Applying for jobs is a full-time job
You still get to use your university letterhead
If you don't get any jobs this year it isn't as apparent that you're "stale" next year


Cons:


Your advisor may be under pressure not to allow this.  It could impact her/his ability to recruit new doctoral students until the old ones graduate.
Your university may not allow this
Your university may charge continuous registration fees


Notes:


Your advisor will have to write in his/her letters that your dissertation is essentially finished. Everyone is familiar with this strategy so it's not a red flag.
