This appears to be a GLib problem, not a Guile problem (which isn't too 
surprising, I guess).  If I use GLib 2.14.4 from MacPorts it hangs like 
this, but if I use 2.14.2 it doesn't.  There aren't any changes between 
these versions that look relevant, and the hang doesn't seem to happen 
if I run under gdb, so I suspect it's timing related.  Perhaps some 
sort of race condition between the Gnucash process and the spawned 
process.
