The sample output is kind of large (>1111 lines, available on request) but here
are some lines which might be interesting:
Sort by top of stack, same collapsed (when >= 5):
__workq_kernreturn (in libsystem_kernel.dylib) 7760
kevent (in libsystem_kernel.dylib) 2659
__open (in libsystem_kernel.dylib) 1806
mach_msg_trap (in libsystem_kernel.dylib) 797
semaphore_wait_trap (in libsystem_kernel.dylib) 12
The thread which has the long wait in __open contains:
1806 -[NSDocumentControllerOpenRecentMenuDelegate
updateMenu:withEvent:withFlags:]
1805 -[NSDocumentController(NSInternal) _populateOpenRecentMenu:includingIcons:]
1800 +[NSDocumentController(NSInternal)
_recentMenuItemTitlesFromLocationComponentChains:includingIcons:]
1800 -[NSFileLocationComponent iconAsAttributedString]
...
1788 __open (in libsystem_kernel.dylib) + 10 [0x7fff8b1c9ad2]
The recents items look like:
file1
file2
...
someFile - folderA
someFile - folderB
...
Both folderA and folderB have their own icon (which is displayed in front of
"folderA" and "folderB").
But other apps with the same two "someFile" show no delay.
Nor does my own debug-version of TextEdit.
Kind regards,
Gerriet.
