### Describe the bug, including details regarding any error messages,
version, and platform.
This is not consistent (re-runs will sometimes resolve it), but we seem to
be getting a segfault when we are running our python-flight tests in R:
```
Start test: flight_put with overwrite = FALSE
'test-python-flight.R:66' [success]
/arrow/cpp/src/arrow/status.cc:134: Invalid: Signal stop source already set
up
*** caught segfault ***
address 0xb8, cause 'memory not mapped'
An irrecoverable exception occurred. R is aborting now ...
Segmentation fault (core dumped)

Error: `docker-compose --file
/home/runner/work/arrow/arrow/docker-compose.yml run --rm -e TZ=MART -e
ARROW_R_FORCE_TESTS=true ubuntu-r` exited with a non-zero exit code 1, see the
process log above.
```
from:
https://github.com/apache/arrow/actions/runs/3851391995/jobs/6562508211#step:7:24718
I suspect that this is the code that is segfaulting (based on the test that
immediately preceded it):
https://github.com/apache/arrow/blob/6bd847b2aefdb0f10eaf83a3bfe2dc8ee269e8e4/r/tests/testthat/test-python-flight.R#L70-L72
Some hypotheses from @paleolimbot :
> It is almost certainly the cancellation stuff that was updated in R and
C++ between the last release and now. Is there any chance that the Python arrow
that's being used is outdated?
> Dewey Dunnington: That seems new...I'm getting it in CI now and I didn't
get before (and the PR that I'm thinking of has been merged for a while)
> Dewey Dunnington: The SignalStopSource already set up message is because
R's cancellation trumps Python's and so we get a warning. The segfault,
however, is definitely new.
