Subject: Make signals from geiser work
X-Git-Tag: v0.2~7
X-Git-Url: https://git.siccegge.de//index.cgi?p=frida%2Ffrida.git;a=commitdiff_plain;h=4e10c813f57981265534133a6d857fd66c6edccc;hp=1b43b26ba9b23cb5f3004db7b9b00f6b08227563

Make signals from geiser work

Move geiser to a proper QThread instead of a guile-only thread. This
way it can properly send/receive signals. Also for some obscure reason
the QVector<int> hack is needed for things to work

Closes T24
