Summary	09016: pegasos2: Freezes MAME if G pressed
Description	When G pressed MAME entirely freezes, requiring the Task Manager be used to kill it off.
Steps To Reproduce	>mame pegasos -nolog It may pause for a moment (or sometimes a lot of moments) while "Initializing KBD". After it says "Entering IKARUS low level console", press G. MAME will immediately stop responding. The -nolog parameter is to prevent the error log filling up to multiple gigabytes while it is doing the "Initializing KBD".
