    <thetext>Some functions in the jsc shell GlobalObject are only added as debugging aids.  They are meant to be used carefully under controlled conditions for test development.  Though they are added as DontEnum, Object.getOwnPropertyNames() still enumerates them.  We should filter out all DontEnum properties of this GlobalObject so as not to trip up fuzzers that try to fuzz with Object.getOwnPropertyNames.
