[racket-dev] SIGSEGV MAPERR si_code 1 fault on addr (nil) when inserting rows via "db" / SQLite

Thanks for the report. Your program led me to find *a* bug (a space leak 
in the statement finalizer thread). Fixing that bug causes your program 
to succeed consistently, but the bug I found should not have caused the 
segfault, and I haven't been able to find an underlying problem. I'll 
push the intermediate fix; if you still run into problems let me know.
