Comment #6 on issue 5452 by [email protected]: V8 Garbage Collector unable
to reclaim local scope 2D contexts fast enough
http://code.google.com/p/chromium/issues/detail?id=5452
Looking at the original page (example.html) I made a reduction
(reduction.html). In
the reduction I create a local variable within a tight loop. I instantiate
a Canvas
and get a 2D context. I then draw to the context and the variable goes out
of scope.
The garbage collector is being hammered by the generation of all of these
shortlived
objects. The original example has two additional arrays plus the DOM
holding
references to the same canvas but that does not appear to be necessary to
see a
problem.
This specific example does not seem very likely but running the reduction
under
Purify may bring to light problems that are worth fixing.
