Hey!
> This is happening in this order, right? Right, plus I don't see the following warning: --8<---------------cut here---------------start------------->8--- warning: call to primitive-fork while multiple threads are running; further behavior unspecified. See "Processes" in the manual, for more information --8<---------------cut here---------------end--------------->8--- so I guess the issue is elsewhere. > POSIX leaves unspecified the behavior of a child process forked from a > multi-threaded process; there could be deadlocks, etc. ‘primitive-fork’ > prints a warning when called from a multi-threaded Guile process. > > The solution is for multi-threaded Guile processes to not fork at all, > or to fork only via ‘open-pipe*’, ‘system*’, etc., which are “known > good” (they take care of post-fork handling in the child and call ‘exec’ > before anything bad could happen.) Thanks for clarifying that anyway. Mathieu
