- Delivery of the newsgroup has been uneven for the last few weeks.]]

- [It's not been so much delivery as posting, due to lessened attention

- Draft 5 of POSIX.1a defines qfork() by saying:
- "The qfork() function shall be identical to the fork() function with
- the following exception: behavior is undefined if the child process
- executes any code between the return from qfork() and the succeeding
- call to one of the exec functions or _exit()."
-
- This seems to be a very harsh restriction. The following code seems
- like it would be undefined:
- status = qfork();
- if (status == 0) execve(...);
-
- I would propose replacing the phrase: "executes any code" with "calls
- any function defined in this standard or the C standard {8}" I think
- that does what you mean.
