Here (Linux) I get the following:

# purge/gc os.path 12
# purge/gc operator 50
# purge/gc io 49
# purge/gc _sysconfigdata 48
# purge/gc sysconfig 47
# purge/gc keyword 46
# purge/gc site 45
# purge/gc types 44

Also, do note that purge/gc after wiping can still be a regular gc pass unless the module has been wiped. The gc could be triggered by another module being wiped.
