1310281 - Jump list features triggers main thread I/O

Status: RESOLVED DUPLICATE of bug 1354143

(Core :: Widget: Win32, defect, P4)

Description

[Bill McCloskey [inactive unless it's an emergency] (:billm)]

I was browsing through Chromehang data today and found this at #4:

    FlushFileBuffers (in kernelbase.pdb)
    CFileStream::_NonTransactedCommit(CFileStream::COMMIT_TYPE) (in shcore.pdb)
    CFileStream::Commit(unsigned long) (in shcore.pdb)
    CDestinationList::_WriteListToFile(unsigned short const *) (in Windows.Storage.pdb)
    CDestinationList::_WriteList() (in Windows.Storage.pdb)
    CDestinationList::CommitList() (in Windows.Storage.pdb)
    mozilla::widget::JumpListBuilder::CommitListBuild(bool *) (in xul.pdb)
    XPTC__InvokebyIndex (in xul.pdb)
    XPCWrappedNative::CallMethod(XPCCallContext &,XPCWrappedNative::CallMode) (in xul.pdb)
    XPC_WN_CallMethod(JSContext *,unsigned int,JS::Value *) (in xul.pdb)
    JS Frame (in xul.pdb)
    Interpret (in xul.pdb)

I don't know anything about jump lists. But do we need to do this on the main thread?
