Well, don't forget to copy the data before free'ing :-)
I haven't really looked at Mach code for a while. Which version of Mach
is this VFS for? It might be relatively easy to port one of the Mach
realloc's to NetBSD (given that it uses Mach-derived VM).
If it were useful, a real realloc() would be cool, otherwise, writing a
macfs_realloc() that does the simple ralloc algorithm might be appropriate.
