It *is* a dangerous trap, mitigated by the fact that our code execs soon after fork, but that’s not great (“A fork() on the Road” explains the many shortcomings of ‘fork’, including how it interacts with multi-threaded code.) As discussed on IRC yesterday, the longer-term approach is to augment Guile is a posix_spawn-like primitive implemented in C. If it’s in C, we can make it do the right thing safely, as is done with ‘open-pipe’. Thanks, Ludo’.
