html-widget choice and use of html2text

Good afternoon all,

I took a new tack tracking down my problem with balsa becoming  
unresponsive when downloading some new messages, and discovered (just  
using top) that when balsa seems frozen, one CPU was pegged running  
html2text.  As that seems only necessary when using gtk-webkt2 on  
html-only messages, I tried recompiling with gtkthtml.   As that didn't  
work, I vaguely recall the discussion deciding to drop it.  However,  
it's mention has not yet been removed from README.

I have not yet delved into the code - but I'm wondering if my problem  
is because of how Balsa calls html2text - possibly in some way which  
prevents any interruptions.  Also, I'd like to confirm that html2text  
is only called on html-only messages.  Related question - why is  
html2text called at all when fetching messages (POP3) from the server.   
I would expect it is only needed when forwarding or replying.  Am I  
missing something.  Separately - I'll have to check the relative  
performance of the other viable html2text solutions.
