perf ui browser: Introduce ui_browser__write_nstring()

2015-08-12T13:27:04Z

To remove direct access to libslang functions, with the immediate goal of implementing horizontal scrolling at the ui_browser level, but also because we may at some point want to implement ui_browser with other UIs in addition to the current libslang implementation.

perf ui/tui: Protect windows by ui__lock

2013-12-26T14:22:01Z

Sometimes perf top TUI breaks display with concurrent help/input window and pr_* messages since they're not protected by ui__lock. You can check it by pressing (and not releasing) 'h' key on a "perf top -vvv" TUI session.
