After intermittent connection failures or target power failures it
might be necessary to try reexamination even when polling fails. This
should make communication with Cortex-A targets more reliable.
This was runtime tested with stlink attached to an stm32l1 and an FTDI JTAG
adapter attached to an stm32f1 target.
