Am I the only one to regard portmaster's lack of a failsafe install as
a significant problem? 

All three tools will make a back-up of an installed package before
deinstalling it and installing the new version. If this fails
Portupgrade and portmanager will immediately restore the backup usually
with no more disruption that a normal upgrade.

Portmaster leaves you to restore the backup manually which is a minor
hassle if you notice it immediately, a problem if you find out the hard
way, and a potential nightmare if you miss it altogether.
