Mark, you're a computer guy, and if I could do graphics here I'd do a standard flow chart. Instead, imagine the circles and diamonds and octogons:
Do you like the job? Y/N
If N, keep looking; if Y, do you want the job?
If N, keep looking; if Y, take it.
Assuming you have some of the ready on hand to float you through the initial period, really mate -- how much worse off could you be 3 months from now?
(You've been on the boards here for around 6 weeks -- seem very long to you?)
Come July your W is still going to be the same WAW she is now, your living arrangements are going to be no less tenuous (and possibly more solid), the global economy is going to be whatever Messrs Brown, Obama, et al., are able to concoct, and someone is saying, "Hey Mark, why don't you come round and fiddle with our computers and get in a couple on the back nine while you're at it?"
