gthread and fork/exec

[lingdanmiaoD netscape net]

Hello,

I am trying to use gthread and fork/exec to have a thread and child
process.  It seems both thread and child process cannot work properly,
namely, there is no new /tmp/testfile generated, and the thread may
not work sometime. It is the same when using g_spawn_ ...

Could somebody take a look?

Thanx a lot!


The following libs are used
    glib-1.3.11
    libpthread.so.0 => /lib/libpthread.so.0
    libdl.so.2 => /lib/libdl.so.2
    /lib/ld-linux.so.2 => /lib/ld-linux.so.2
