Detailed Description

Global string buffer for the StringAtom system. This is where all raw strings for the StringAtom system are stored. If enabled, the StringBuffer can grow, but it may never shrink. Once a string is in the string buffer, it cannot be removed. String data is simply appended to the last position, strings are separated by a 0-terminator-byte. A string is guaranteed never to move in memory. Several threads can have simultaneous read-access to the string buffer, even while an AddString() is in progress by another thread. Only if several threads attempt to call AddString() a lock must be taken.

NOTE: NOT thread-safe! Usually, GlobalStringAtomTable cares about thread-safety for the global string buffer.
