Warning: On 32-bit GNU/Linux x86,
you must be careful not to set memory usage too high.
glibc may allow the process heap to grow over
thread stacks, which crashes your server. It is a risk if the
value of the following expression is close to or exceeds 2GB:

innodb_buffer_pool_size
+ key_buffer_size
+ max_connections*(sort_buffer_size+read_buffer_size+binlog_cache_size)
+ max_connections*2MB

Each thread uses a stack (often 2MB, but only 256KB in MySQL AB
binaries) and in the worst case also uses
sort_buffer_size + read_buffer_size additional
memory.
