I've got another one, faster, and better.
Hardware reset working, no GPIO leaking.
Got around 1.215 mA at 3.3V but the board I test has 16MB Flash, and some neopixel, could be leaking more, I've cut ADC and power led, still...

Code:

PSM_FRCE_OFF = 0x40010004mem32[PSM_FRCE_OFF] = 0xFFFFFFFF
P.S. Actually there is some GPIO "leaking" but it looks to be the default pull-down... blimey. :)
