Comment 5

[Lars T Hansen]

Could look like a regression in #464643 that should not be allowed to escape.

Attachment: Part 1 of 2: Merge latest performance suite changes

Need to get the performance changes into TC before the big merge so that we can get a proper snapshot of TC prior to redux changes.

Attachment: #2 Merge "test" directory from redux into central

Merge the testcase changes from the following changesets.

changeset:   1129:da7e948b236d
user:        Erik Tierney <[e-mail]>
date:        Thu Nov 20 13:58:18 2008 -0500
summary:     Fix bug 464957 - can't throw exceptions from the callback method, since it can be invoked while making an allocation.  Instead just swallow any exceptions.  Fix missing write barrier in NewObjectSample.  (r=treilly)

user:        Steven Johnson <[e-mail]>
date:        Thu Nov 20 12:14:19 2008 -0800
summary:     Sometimes a client of Tamarin will need to know if an object is a global object
