One important thing I didn't realize until now: the whole build process was run under strace(1). (Don't ask me why. (In short, this was build-time dependency analysis.)) So I tend to blame strace now, since it does some clever mangling which affects process control behaviour, which in turn could affect configure tests: If the parent process decides to wait(2) for a child that is currently being traced, it is suspended until an appropriate child process either terminates or incurs a signal that would cause it to terminate (as determined from the child's current signal dis- position). Now I'm trying to find out the exact reason.
