No, not block, just reuse the already-opened environment. When BDB opens
our FS environment, it mmaps the environment files. That's just fine on
most systems, but HP-UX does not let you map the same file into a
process twice. So my longish-term plan is have a reference-counted cache
of open environments, and avoid the second (and third, and fourth...) mmap.
