I think you have misread the code.
(Which distcc version are you using? Though this code hasn't changed
between distcc 2.18.3 and distcc 3.0.)
The code does the following (this is in dcc_lock_one() in src/where.c):
while (1) {
for (i_cpu = 0; i_cpu < 50; i_cpu++) {
for (h = hostlist; h; h = h->next) {
The middle loop is over slot number. The inner loop is over hosts.
It tries slot 0, host 0, and then slot 0, host 1, and then slot 0, host 2,
etc.
before trying slot 1, host 1, and then slot 1, host 1, and then slot 1, host
2, etc.
(Yes, this code won't work if you have a single host with more than 50
slots! Patches welcome :)
