The reason for this was that if you the root file system was low on
space, the delay between VOP_UNLINK and actual space being reclaimed
when running with soft- updates could cause 'make installworld' or
'make installkernel' to fail.  When softupdates were first introduced,
the default size for the root file system in sysinstall was 32 MB.

I don't know if the delete / create race has been fixed, but the
default size for the root file system is now 256 MB, and a default
installation uses less than a quarter of it.
