Would it be satisfactory if I provide a flag in vm parameter 48 that, if set, indicates the itimer heartbeat is in use? This could be done in a few minutes and would be ready for the official release of Pharo 6.

Effectively, yes. It would be set in VMs that use the itimer heartbeat. Currently that's only a subset of the Linux VMs. Hopefully it will not be set in any vm soon :-)
