Paul,
For the first time, I benchmarked concurrent linux client write
access over a SAMBA network share, and it worked, 0 data loss.
This is opposed to a

Hi, Tim!
I'd like to use BerkeleyDB! But have you test it in mod_perl environment?
Not yet, but I will be very soon. I'm sure others are using it.
May be I wrote scripts in wrong fasion.
I open $dbe and $db at startup.pl

Hey,
I'm working on a new module to be used for mod_perl style
caching. I'm calling it MLDBM::Sync because its a subclass
of MLDBM that makes sure concurrent access is serialized with
flock() and i/o flushing between reads and writes. Below is
the code for the module. I believe it could
