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 | |
7 | # | |
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 | |
13 | # can happen. | |
14 | # | |
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 | |
