>Description:

After updating to todays -current on this machine (this is a CubieTruck,
dmesg at: https://netbsd.org/~martin/evbearmv7hf-atf/dmesg.txt)
atf tests hang here:

lib/librumpclient/t_exec (442/847): 5 test cases
    cloexec: [1.106553s] Passed.
    exec: [1.120590s] Passed.
    noexec: [1.108296s] Passed.
    threxec: 

... indefinitely untill the rump_server process is killed with -9.


>How-To-Repeat:

Not sure:	cd /usr/test/lib/librumpclient && atf-run t_exec

>Fix:
n/a

 The machine later locks up completely (can't break into ddb), so there is
 not only a rump issue...

 I also see this on a dual macppc machine.

 Side note:
 when the test is busy looping for hours you can do "top", but avoid "ps",
 the latter prevents any other processes from being created instantly.
