Hmm, I consistently see 

FAIL: gdb.mi/mi-console.exp: Testing console output
FAIL: gdb.mi/mi-console.exp: Finished step over hello (timeout)

FAIL: gdb.mi/mi-syn-frame.exp: testing exec continue
FAIL: gdb.mi/mi-syn-frame.exp: list stack frames

if I run the complete testsuite, since this was checked in.

Funny thing is that if I run mi-console.exp alone, it usually
(although not always) succeeds.

Attached are a gdb.log for a failing run and a passing run.
