Which you seem to think is a bad thing, yet is actually a very good thing because it means that crashes are repeatable and problems are debuggable from end user reports.
Trying to randomize filehandles for the general case is not a productive activity. If you want to debug cases write yourself a glibc wrapper that does annoying things but don't inflict it on people who actually want to build working, testable, debuggable systems (ie most of us)
