[MlMt] big sur, new message view window issue

[Marco Qualizza]

I'll chime in here with my own observations:

* The processes seem to be related to opening new emails (I get both an 
"about:" and some number of MTLCompilerServices)
* The processes don't seem to spawn when opening a previously-opened 
email
* W.R.T. memory consumption -- I haven't noticed whether the memory used 
by the processes depended on the size of the email, but I have seen 
MailMate's memory usage (as reported by iStat Menus) exceed 15GB -- I 
now periodically check, and restart the app when it gets near 10GB (I'm 
restarting at least daily).  Currently, it's at 4.9.


Cheers!
Marco
