profiler: flush after writing the profiler output
Otherwise, the profiler output might only partially appears until the next flush
of the buffer. Since profiling often happens for long operation, the next flush
can be a long time away.
Test the extensions.afterloaded() function
$ cat > foo.py <<EOF
> from mercurial import extensions
> def uisetup(ui):
> ui.write(b"foo.uisetup\\n")
> ui.flush()
> def bar_loaded(loaded):
> ui.write(b"foo: bar loaded: %r\\n" % (loaded,))
> ui.flush()
> extensions.afterloaded(b'bar', bar_loaded)
> EOF
$ cat > bar.py <<EOF
> def uisetup(ui):
> ui.write(b"bar.uisetup\\n")
> ui.flush()
> EOF

Test afterloaded with the opposite extension load order

Test the extensions.afterloaded() function when the requested extension is not
loaded
$ cd ..

Test the extensions.afterloaded() function when the requested extension is not
configured but fails the minimum version check
$ cd ..

Test the extensions.afterloaded() function when the requested extension is not
configured but fails the minimum version check, using the opposite load order
for the two extensions.
