perf lets you decide to only get events that concerns a single process
and thus make sysprof profile this process instead of the whole system
(it can happen that you don't really care about other processes that are
just then noise).
As a side effect, this allows sysprof to not run as root if you have the
rights on the process you want to profile.
Accessibility prevents sysprof from working reliably, so disable
it. Specifically, it
- causes large amounts of time to be spent in sysprof itself
whenever the label is updated.
- sometimes hangs at shutdown
- does long-running roundtrip requests that prevents
reading the event buffers, resulting in lost events.
We do this by putting the samples label and a sizer label into a
notebook where show_tabs is false. The benefits of this is that w
avoid the hack of connecting to the size request signal, and that the
samples label will be right adjusted.

Valgrind:
* binparser.c (bin_parser_free): Add this function
* elfparser.c (elf_parser_free): Call bin_parser_free()
* sysprof.c (compute_text_width, add_text): Plug leaks
* collector.c (add_trace_to_stash): Copy n_addresses to a stack
variable instead of reading it out of the mmap'ed area all the
time. (That way if there is an overrun, we won't write too much
into the address array).
2006-10-26 Soren Sandmann <sandmann@daimi.au.dk>
* module/sysprof-module.h (struct SysprofStackTrace): Increase the
max number of addresses to 1021, reorganise SysprofMmapArea to
make the traces naturally page aligned.
* TODO: Update
2006-10-09 Soren Sandmann <sandmann@daimi.au.dk>
* profile.c (profile_list_callers): Make this function return a
list of immediate callers again.

* process.c (get_kernel_symbols): Only attempt to read the kernel
symbols once.
