Release 0.4.4

FLOPP 0.4.4 has been released. It corrects a bug on FreeBSD 4.x with pthread_detach causing a memory leak. The clients list is now preallocated on startup, which speeds up the process, but uses more memory. In next version, a "PREALLOCATE" directive will be useable to choose between both versions. And still to do the control of SIGHUP, in order to create the 0.4.5 release (and probably the 1.0 if it is stable). A parallel branch will be created then, implementing a pool of threads (as FLOPP 0.3 was doing) instead of a thread/client which is not usable for large systems and can cause DoS with clients waiting for timeout.
