A couple of times while experimenting with hastctl wedged with ctrl+t

Trying to run gstat to see what the disks might be doing, has it stuck in

load: 0.07  cmd: gstat 1362 [g_waitfor_event] 207.47r 0.00u 0.00s 0% 2520k
load: 0.07  cmd: gstat 1362 [g_waitfor_event] 207.69r 0.00u 0.00s 0% 2520k
load: 0.07  cmd: gstat 1362 [g_waitfor_event] 207.87r 0.00u 0.00s 0% 2520k
load: 0.07  cmd: gstat 1362 [g_waitfor_event] 208.04r 0.00u 0.00s 0% 2520k

Anyone know what might lead to this deadlock ?
