Check in "unique, but sharable" optimization to ISOHM code, which allows object header messages that are only used in one object to remain in the sole user's header, but migrates messages that are used in more than one header into the ISOHM heap. Tested on: Mac OS X/32 10.4.9 (amazon) FreeBSD/32 6.2 (duty) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
