22 * This is a fairly high-level type of critical section. It ensures that no
23 * two threads work on the netconfigs files at the same time. Since we do
24 * so many things inside these, here are the rules:
25 * 1. begin_critical_section(S_NETCONFIGS) *before* begin_ any others.
26 * 2. Do *not* perform any I/O with the client during these sections.
