please take a look at this proposed addition to UL. This adds a number of
trace points to thread creation. In detail:
- it traces thread creation and thread creation errors, including pthread
attributes (for Posix platforms)
- it traces stack location and creation/removal of stack guard pages.
This all was first AIX-only tracing, but I converted this to UL and made it
available on all platforms.
Note also that I added a helper function, os::errno_name(), which is a very
simple replacement for strerror() without its problems (thread safety,
What do you think?
Kind Regards, Thomas
