Hi Paul, thanks for remark my post! :) The important here is that David Lewis has confirmed it fix the problem, http://forum.world.st/OSProcess-error-in-1-3-tp4602389p4607494.html

Just test change ThisOSProcess>>startUp: and see what happens :) ThisOSProcess>>startUp: resuming | aio | (aio := Smalltalk at: #AioEventHandler) ifNotNil: [ aio startUp: resuming ]. *OSProcessAccessor initialize.* self initializeThisOSProcess HTH Regards. 2016-06-08 15:12 GMT-03:00 Paul DeBruicker <pdebr...@gmail.com>: > Hi Sabine, > > I had a Pharo 5 image where running > > OSProcess waitForCommand:'ls' > > twice would lock everything up. > > Following Gaston's suggestion here: > > > http://forum.world.st/Problem-with-delay-waiting-OSSubprocess-code-on-Pharo-5-0-td4895780.html#a4898158 > > Fixed it for me.
