Subject: If a frame has already been loaded don't do it again.
X-Git-Url: https://git.cworth.org/git?a=commitdiff_plain;h=99f84fa0e278f4ca30577c22ede85c643c6017cc;p=apitrace

If a frame has already been loaded don't do it again.

In particular for searching we kept reloading frames over and
over again.
