25c0d1a18a The code is correct as it contains an assert(3) in the "default" switch 
case, but GCC 4.3 is not able to detect this and instead complains
with "warning: 'amode' may be used uninitialized in this function".
Hence, although the assert(3) already protects the code here, get rid of
this compiler warning by doing a simple initialization of the "amode"
variable. (CVS 4436)

locks and causing database corruption.  Nevertheless, it would be good
if we could figure out a way to report errors when closing a file from
the wrong thread. (CVS 2946)
