[nRF51822] SENSE pin in PORT mode doesn't solve the GPIOTE overconsumption in EVENT mode

The hardware bug #39 on the GPIOTE in EVENT mode which gives a overconsumption of ~1mA even in idle mode on, kills the interest of having a low power chip, because the solution gived by Nordic which is to use the PORT interrupt mode on a pin with SENSE mode enabled, doesn't works when I use multiple interrupts with short transition signals. When I read the NRF_GPIO->IN, the signal may have has already gone down because I have lost some interrupts occurences.

Could you please recommend another way to deal with interrupts, still staying in low power ? Thanks,
