run-tests: bump the default timeout on Windows to 4x the normal value
There are a ridiculous number of tests that timeout on Windows with the 360 sec
default (~60). And because of the bug where timed out tests still run to
completion before the results are thrown away[1], the timeout does nothing but
waste time, so there's no reason to try to find a lower value that still works.
For reference on my system:
# Ran 909 tests, 116 skipped, 119 failed.
python hash seed:
2052473208
real 151m44.322s
user 0m0.077s
sys 0m0.046s
[1] I thought that I wrote a bug for this, but search isn't finding it.

'''measure performance of Mercurial commands
Using ``hgperf`` instead of ``hg`` measures performance of the target
Mercurial command. For example, the execution below measures
performance of :hg:`heads --topo`::
$ hgperf heads --topo
All command output via ``ui`` is suppressed, and just measurement
result is displayed: see also "perf" extension in "contrib".
Costs of processing before dispatching to the command function like
below are not measured::
- parsing command line (e.g. option validity check)
- reading configuration files in
But ``pre-`` and ``post-`` hook invocation for the target command is
measured, even though these are invoked before or after dispatching to
the command function, because these may be required to repeat
execution of the target command correctly.
