With latest MSVC toolchain, the timeout handler takes 2 hours to complete. Checking the process.html file, we can find the following text:

0:048> cdb: Reading initial command '.dump /f core.46216;qd'
*****************************************************************************
* .dump /f is not supported on a user mode process. *
* *
* .dump /ma creates a complete memory dump of a user mode process. *
*****************************************************************************

                ^ Extra character error in '.dump /f core.46216;qd'
0:048> WARNING: tool timed out: killed process after 3600000 ms
----------------------------------------
[2023-11-22 22:36:16] exit code: -2 time: 3599998 ms

This is repeated twice for two processes, taking up a total of 2 hours.

We should update the dump command to use /ma instead of /f.
