So this times out after 10 seconds? ... this is likely plenty on a
normal host, but we run the tests on overloaded CI systems sometimes,
where 10 seconds are not that much...
I'd suggest to replace the condition in the for-loop with "i < 30000" or
even "i < 60000", just to be sure.

Sorry for being pedantic, but I'd really prefer to write it without
side-effects in g_assert() please. (same for the other occurrences in
this patch)
