If forced writes are on and working this problem won't happen.
However, during the development of V2.1.x of Firebird, the
developers tried a performance comparison of Firebird on Linux
with forced writes on and off. They were the same! Unfortunately
that was the indication of a bug in the Linux kernel, not a
wonderful optimization of disk handling. Check the 2.1.x
release notes for more details - page 23 - and suggestions for
making disk writes more reliable even with older Firebirds.
