2 # as of 2.09 on win32 Storable w/threads dies with "free to wrong
3 # pool" since it uses the same context for different threads. since
4 # win32 perl implementation allocates a different memory pool for each
5 # thread using the a memory pool from one thread to allocate memory
6 # for another thread makes win32 perl very unhappy
8 # but the problem exists everywhere, not only on win32 perl , it's
9 # just hard to catch it deterministically - since the same context is
10 # used if two or more threads happen to change the state of the
11 # context in the middle of the operation, and those operations aren't
12 # atomic per thread, bad things including data loss and corrupted data
15 # this has been solved in 2.10 by adding a Storable::CLONE which calls
16 # Storable::init_perinterp() to create a new context for each new
17 # thread when it starts
