# Bug#27322 failure to allocate transaction_prealloc_size causes crash
#
#
# Manual (6.0):
# Platform Bit Size  Range                      Default
# 32                 1024-4294967295 (4 Gi - 1) 4096
# 64                 1024-18446744073709547520  4096
#
# Observation(mleich):
# 1. - Linux 64 Bit, MySQL 64 Bit, 4 GiB RAM, 8 GiB swap
#    - SET SESSION transaction_prealloc_size=1099511627776;
#      SHOW PROCESSLIST;

#      1099511627776
#      very short runtime in 5.0
#      excessive resource consumption + long runtime in 5.1 and 6.0
# 2. - Win in VM, slightly older version of this test, MySQL 5.0
#    - testcase timeout after 900s

# There is a significant probablitity that this tests fails with testcase
# timeout if the testing box is not powerful enough.
