Hi,

src/log.c has the following construction:

while (waitpid(pid, &status, 0) != pid);

To my understanding, this will spin until waitpid() returns pid, but
it will spin forever if waitpid fails.

Shouldn't there be a check for error return, for example if the child
is already dead by the time we reach this code?

Greetings
Marc, by all means not a C programmer
