Disabling in normal mode.

Pretty much every page make the virtual size spike up.  Not necessarily to
25GB, but it is relatively common.  Just now, the "main" process has 13GB virt
/ 1.1GB rss.  I opened a new tab, and the virtual size jumped to 19GB.  Closing
the tab and opening a new tab again, didn't do it.  Waiting 20 minutes and
opening a new tab did it again.

I have no idea how to read this or what to look for.

FWIW, it says:

 WARNING: the 'heap-allocated' memory reporter does not work for this platform
and/or configuration. This means that 'heap-unclassified' is not shown and the
'explicit' tree shows less memory than it should.
