My last email was premature, because the exact same thing happened again: it hung at 2:15 minutes of CPU time. Fortunately I was able to kill it and retry, and thanks to multithreading, you don't have to wait anything like two minutes before reaching the two minute mark.

It's reproducible enough that I can feel confident that HOL will build only when the activity monitor shows that the process has consumed at least three minutes of CPU time. But I haven't seen it for a couple of weeks.
