Having these named differently than the test itself mostly creates unecessary confusion and makes writing logic against the tests harder so let's rename the testsuite-xx units and scripts to just use the test name itself.

|
|
#
|
|
# When bash is waiting for an asynchronous command via the wait builtin,

|
# the reception of a signal for which a trap has been set will cause the wait
|
|
# builtin to return immediately with an exit status greater than 128,
|
|
# immediately after which the trap is executed.
|
|
#
|
|
# In other words - every time we propagate a signal, wait returns with
|
|
# 128+signal, so we have to wait again - repeat until the process dies.
