Description
Whenever I save changes to a source file change the entire IDE locks up for a couple seconds. And one time while it was locked I pressed several keys (mostly up/down arrow keys) and in that case, after the hang during save finished, the IDE completely lost touch with the keyboard - only mouse interaction worked. I had to restart qtcreator to get keyboard interactions working again.
I've reproduced the issue in 2 scenarios:
1. with a simple cmake project
2. with a larger qmake project (I haven't tried a smaller/simpler qmake project)
In the cmake project the hang during save problem went away when I changed the build step to use `make` instead of `cmake --build`.
The qmake project already uses `make` so I haven't changed anything in the project build steps in the qmake project.
I've attached an strace.log file which was generated during a save operation. As far as I can tell the save begins with the first access("/home/schidester/development/git/Bumblebee/src/Bumblebee.cpp", W_OK) = 0 line.
I can't tell where in the strace.log the save finished.
I installed Qt and qtcreator via `qt-unified-linux-x64-2.0.3-1-online.run` a few days ago and this is on a freshly installed OS (just updated to CentOS 7 via clean install). I've also removed and reinstalled Qt and qtcreator (using the same installer).
