[Rd] tools::startDynamicHelp(): Randomly prevents R from exiting (on MS Windows)

[Henrik Bengtsson]

Thank you for confirming this. I just filed PR#18650
(https://bugs.r-project.org/show_bug.cgi?id=18650).

FWIW, I've found two other issues with startDynamicHelp() prior to this:

* https://bugs.r-project.org/show_bug.cgi?id=18645
* https://bugs.r-project.org/show_bug.cgi?id=18648

> ISSUE: On MS Windows, running cmd.exe, calling Rscript --vanilla -e "port <- tools::startDynamicHelp(); port; port <- tools::startDynamicHelp(FALSE); port" will sometimes stall R at the end, preventing it from existing. This also happens when running R in interactive mode. It seems to stem from calling tools::startDynamicHelp(FALSE). Before filing a formal bug report, can someone please confirm this behavior? You might have to call it multiple times to hit the bug. DETAILS: Microsoft Windows [Version 10.0.19045.3803] (c) Microsoft Corporation. All rights reserved.
