I tried running it outside of atf, as follows:
% setenv RUMP_SERVER unix://csock
% rump_server -lrumpnet -lrumpnet_net -lrumpnet_netinet -lrumpdev \
It fails during initialization unless you unlimit maxthread (since it
creates a lot of threads)... after that it was hanging every time, in
what turned out to be the rump_sys___sysctl() call in getproc() in
h_execthr.c... for some inexplicable rump reason, as killing and
restarting the rump_server made it start working. Now it runs
I'm going to make it print what it's doing in the hopes that we can
get a line on where it's hanging when it happens in a full test run.
