11833	Deadlocking while loading a lot of data	naoliv	team	"It seems that JOSM is deadlocking while loading a lot of data.

For example, trying to load all `boundary=administrative` in Brazil (this file http://naoliv.iq.unesp.br/osm/boundaries.osm.bz2 - size is 21M).

Until some time ago I used to see JOSM freezing sometimes while trying to load it. But most of the time it was able to open it.

Now it is always freezing here.
Two CPU cores at 100% and with strace it's possible to see that it's stopped at this:

`futex(0x7f4dcce979d0, FUTEX_WAIT, 25833, NULL%` 

Stopped in futex always makes me think that somehow the program is deadlocking.


Is there anything that I can do to help debugging this?
