We enable interruptible system calls before the read(2) so that if

we can process the death(s) and return tokens to the free pool.
Once we return from the read, we immediately reinstate restartable
system calls. This allows us to not worry about checking for
EINTR on all the other system calls in the program.
There is one other twist: there is a span between the time
reap_children() does its last check for dead children and the time
the read(2) call is entered, below, where if a child dies we won't
notice. This is extremely serious as it could cause us to
deadlock, given the right set of events.
To avoid this, we do the following: before we reap_children(), we
dup(2) the read FD on the jobserver pipe. The read(2) call below
uses that new FD. In the signal handler, we close that FD. That
way, if a child dies during the section mentioned above, the

/* The acquire algorithm goes like this (from job.c):
Read a token. As long as there's no token available we'll block. We
enable interruptible system calls before the read(2) so that if we get a
SIGCHLD while we're waiting, we'll return with EINTR and we can process the
death(s) and return tokens to the free pool.
Once we return from the read, we immediately reinstate restartable system
calls. This allows us to not worry about checking for EINTR on all the
other system calls in the program.
There is one other twist: there is a span between the time reap_children()
does its last check for dead children and the time the read(2) call is
entered, below, where if a child dies we won't notice. This is extremely
serious as it could cause us to deadlock, given the right set of events.
To avoid this, we do the following: before we reap_children(), we dup(2)
the read FD on the jobserver pipe. The read(2) call below uses that new
FD. In the signal handler, we close that FD. That way, if a child dies
during the section mentioned above, the read(2) will be invoked with an
invalid FD and will return immediately with EBADF. */
