On we go. 0.5.9 contains the necessary fix for Windows to not blow up the debugger in regular intervals. The macOS fix is also coming along however there is still a little bit of work to do (probably a matter of days) until everything is in order; the Mach API is powerful but can be a bit inconvenient at times.
I've done a few quick additional manual tests on the HMH codebase and haven't found any disastrous failures.
Short Changelog for 00.05.09
* [Windows] Inject a debugger owned thread into the debuggee to execute code instead of hijacking debuggee threads
