The meanings of Boaz and Jachin

I've just read Russell Hoban's The Lion of Boaz-Jachin and Jachin-Boaz...

The names Boaz and Jachin are not explained anywhere in the book; where they come from is the names of the pillars at the entrance of King Solomon's Temple (I Kings 7:21):

He set up the pillars in the porch of the temple: he set up the right pillar, and called its name Yāchin, and he set up the left pillar, and called its name Boaz.

וַיָּקֶם אֶת-הָעַמֻּדִים לְאֻלָם הַהֵיכָל; וַיָּקֶם אֶת-הָעַמּוּד הַיְמָנִי, וַיִּקְרָא אֶת-שְׁמוֹ יָכִין, וַיָּקֶם אֶת-הָעַמּוּד הַשְּׂמָאלִי, וַיִּקְרָא אֶת-שְׁמוֹ בֹּעַז׃

There is debate among the commentators as to what these names mean, but in most cases I have my doubts about them. Then, in the last year, I came across a cool explanation that hung together really well, but can't remember what it was. Aaargh, how annoying! Anyone here have a candidate explanation they'd like to offer?
