:I'm starting to suspect that this is the case, and that the signal
:is SIGCHLD. The process does spin off child processes, and there may be

    Another thing you can do, if you want, is block all signals during
    the select using sigprocmask().  But this entails three system calls
    ( sigprocmask(), select(), sigprocmask() ) instead of two in the nominal
    case ( gettimeofday(), select(), [ gettimeofday() if select() returns
    that it was interrupted ] ).
