I've got this working. The tricky part was a driver/application can mix malloc forms. If the driver links against this library all the allocations come from the OS service, but if a protocol or EFI boot service return an allocated buffer it will still use the EFI allocation. The gasket code can detect this and do the right thing, as the emulator is passing up the memory map to EFI.
You can now use the OS based malloc debugging tools in an EFI driver or appliaction. On OS X this is libgmalloc, also called guard malloc.

Start using MdeModulePkg MetronomeDxe driver. Add PEI and DXE_CORE TimerLibs that just call back to the emulator. Add a DXE/UEFI TimerLib that also does a gBS->WaitForEvent() if the stall is for a long period of time. Change the Thunk API for Sleep to nanoseconds.

This implementation only covers a few BaseMemoryLib functions.
The implementation leverates malloc/free in stdlib.

Update the InOsEmuPkg to properly function with XIP. Make the Recovery FV read only. Remove the use of global variable writes from XIP code. Add a new global page that can be used in place of writting to the FD by XIP code. Think of this global page as a system SRAM.
